Not talking to a wall. Actually watched the entire video. Good job again, Paul. Thanks. Love your series.
true...but when you think about he really is
@@anews4898 he is talking to camera.
Definitely second this post. You are a great teacher and you make me laugh a lot while I’m learning along. Thank you!!
Me too
When i bought arduino i couldnt even turn on an LED. Thanks to you Paul i now can do everything you taught me.
P. S im 13 years old
im 11 and im learning soo much for him
im 12😜😜
@@anews4898 im 11 too
Same! I love these videos
im 69
I have ADHD and getting started seemed very daunting until I found your videos - I'm following along, doing all the homework & trying stuff out when I finish. It's a lot of fun. Thank you!
I'm a10 years old and when you said linear equation I was going to quit but you explained very vell that I little bit understood what is linear equation thanks for such tutorials
im 11 and i enjoy is tutorials to!!!
Hey I'm ten too!
Nice job. I'm currently 13. i bet when you become 13, you will be much better than what i was at 13. keep going. and if you have not watched the 13 other episodes i REALLY recommend that.

Keep it up buddy. I am in college now and if you're still interested in Arduino and Raspberry Pi you could pursue Internet of things technology and embedded systems!
Lessons are great! As someone who loves to completely understand why things do what they do I really appreciate you going through the math on this instead of just saying "Put these numbers in and it'll work". Keep up the great work and I'm having so much fun learning how to do this!
My pleasure!
I got my Arduino only five days ago but learned already about dimmable LEDs. What a great lesson! Love the integration of circuit design, math and coding. Wish this kind of educational stuff was available when I grew up. It gives me confidence that our grandchildren won't have to plow through boring electronic books. I think when I am done with all your tutorials (hopefully by the end of the summer) , you will succeed in getting me "to think like an engineer". As the Chinese say: 活到老学到老, never too late to learn. I am 74.
Keep it up fire
Paul, your videos are amazing, and you are a great teacher! I’m a chemical engineer, but never did match with electrical or coding until my current job. I’m now doing plc programming and wiring up level and pressure, transmitters, et cetera, There isn’t much good information on the Internet in terms of basic instruction. My son as a freshman electrical engineering student and had a semester project based on the Arduino last year. After watching what he was doing, and realising how similar it is to PLCs, I bought a kit and started playing around with it just to get more familiar with electrical and coding. Then I found your tutorials. You have a great mix of immediate hands-on instruction, but with the math and physics mixed in. I find most tutorials limited in value because they mostly just do the hands-on part. So far your progression of skills has been spot-on.
I watching this video on 22 April 2024 and I have watched the whole video and learn enjoy both. Love from India
Hi Paul! I was a 13 year old teen bored at home this summer in quarantine ... I randomly found your videos one day and instantly had to get an arduino super starter kit. Trust me you are not talking to a wall at all. I 100% consider you a teacher and more, always making sure to do that homework! Thanks for giving me and many others something fun and exciting to do this summer :).
I just turned 64, and before these videos, I couldn't even spell LED, and now I can turn them on and off.
Seriously, you are helping me figure stuff out so I can light my model spaceships and do cool things. Thanks, You ain't talking to a wall. 64,342 views!
I am an electrical engineering student and have learned more watching your videos than I have attending classes, so please keep up the good work.
Paul McWhorter, I was looking around on your channel and it seems like I will be hanging around for a while, almost all of your videos are things that I am interested in and want to learn. I hope going forward you will keep putting out great content. Thank You, Richard Monseglio

Thank you Paul, you are a great teacher, being a former Instructor in electronic technology for 13 years, and understanding how valuable it is for a student to have the lessons broken down practically and with examples, it allows me to recognize the quality in your instruction!
Wow, thanks!
Paul, you're a great teacher. You're not talking to a wall. I'm actually learning practical engineering from you. I'm an aerospace engineering major and hope to learn more about electronics from your series. Honestly, you made my day when you said, "I want to teach you engineering." Thanks a lot for your effort!
+1
You are not talking just to talk. I watch the full video and do the homework assignments you give out. This series has been really helpful and I appreciate all the work and time you put into it.
Wow, thank you!
Ditto!
These lessons went in just the way I was hoping! Right as the potentiometer was introduced, I had the same idea.
Great!
Good that you explain the Math and not only showing the Map function. So anybody knows more what the Arduino is doing in the background when useing the map function..
i do the projects, and the homework. I love where you have taken the series. Occasionally I do find myself yelling at the screen when i see a mistake lol, but you always catch them and usually before I do. Great job thank you for your hardwork!!!!
I'm an old guy (69) who studied electronics when vacuum tubes were in vogue. (long time ago.) I built my first digital circuit with simple switching transistors , capacitors, resisters etc. My first chip experience was with the NE555. (also a long time ago) I'm studying along with you and am on project 144 as I write this. I am fascinated with micro processors and their uses in hobby projects. You asked if anyone was out there? YES! I'm here. I've programmed some in BASC but this is really quite different. (to me) I enjoy the course and am committed to the end. Thanks for producing it.
The point you made from 6 mins 30 seconds onward is what i feel makes you stand apart from other and a great teacher. To understand something truly we should know it's building blocks, now there might be a short cut to get to an end result but leaning on short cuts doesn't help in doing something substantial in any field. Thank you Sir, your videos are helping many a guys like us learn amazing things! ❤️👍
Great lectures Paul. They are better than all of my Arduino books put together. I'll stick with you and do all of the projects. I'm 73 and a retired engineer (UK) but have always struggled with digital electronics. Regards.
Thanks again Paul, I am enjoying every moment of your course I am on lesson 14 now and must say I am learning a lot. You are the best Teacher ever.
Great to hear!
This is exactly why I call this app UA-cam University. I can research topics that interest me in a timeframe that works for my daily schedules. Paul, here’s a little gift for a few iced coffee’s. Your value that you bring as an education to these topics far outweigh this token but I just wanted to give a small appreciation for your clear and concise teachings. I appreciate that you reiterate certain concepts over and over to really get us into the habit of coding and learning to use the arduinos the right way. I’m watching this videos 4 years after they were made but they are exactly what I needed now that I’ve picked up this new hobby. This channel is an absolute goldmine.
Really appreciate the kind words and support. Thanks!
I actually sit and listen to the whole video. I need to spend more time with you. I absolutely love the videos! I love the math, engineering, physics, coding, circuits, etc.
Thank you for such a wonderful series!
I didn't know anything about Arduino and also programming until 4 days ago, and now with the help of your wonderful tutorials, I am getting better every day.
I don't think anyone can teach this better than you.
Welcome aboard!
YES , YOU ARE ACTUALLY HELPING ME TO LEARN THIS VERY ACTIVELY!

Another great video. You certainly are not talking to a wall. I appreciate your in depth instruction and all the math. Most other instructions assume far too much and you get nothing out of it. Yours is composed of true in-depth lessons and not how-to hacks. The majority of the comments below reflect our appreciation for your quality instructions. Please keep up the great work in providing these wonderful lessons.
Never knew the day when I would actually understand and be able to do what a teacher did on a youtube tutorial series. Keep up the good work. You explained really well and thanks. Gonna watch all these tutorials now.
I am really happy. I only listened to the beginning of the problem, I paused the video and managed to do the project and the code without having to watch the whole video.
After that, I watched the whole video and realized that my reasoning was correct.
Thanks again teacher.
A hug from Brazil
Return Hug to you!
Awesome. I'm learning from scratch. Already watched the first series and I really enjoyed it.
Trust me, you don't talk to a wall. Thank you SO much for your good work.
(from Montreal, Quebec).
your right he's talking to a camra
Hey Paul, your videos teached a 37 old man (that's me) to make a dimmable LED during COVID-19 days. And thanks to you I'm now a Caffeine addict LoL.
Thank you, Paul. You are the best teacher I have ever had in this life. You do not just give us the answer but you actually tell us why it is the answer and push us to Think critically and logically. I have learned many thing with you, and you actually gave me the confidence that I can do it too. Thank you from the bottom of my heart.
Thank you for the kind words of encouragement.
recently unemployed i bought an arduino kit to tinker with in the meantime. i watch every video to completion and am aghast at how clear these these explanations are, so thanks again!
Excellent!
I started watching this series of videos yesterday, they took me back to 1981 and my programming in Basic days on a Vic20.
I ordered an UNO kit last night via Amazon and it's already arrived. I know what I shall be doing during the next few weeks of lockdown :) Thank you for the great tutorials.
Its reminding me very much of 'C', which I learned 30 years ago and haven't used for about 25.
OMG I got a TI99 in 1982, a Vic20 in 1983, and a C64 in 1985. Never spent much time trying to program. Played games mostly! Remember the Mattel Electronics Aquarius computer? The Timex-Sinclair that had little chicklet keys, and only had black and white display capabilities? Ah, the 80s.
@@DeeGeeDeFi I went down the VIC20 followed by C64. I spent hours typing in Basic code from magazines, more hours debugging it all only to get a ball to bounce up and down. I learnt an awful lot about code ( and about my patient wife)
The richer kids got the C64. We got the V20. It was a real treat to hood up the the phone and upload and download new programs. You hoped that it wasn't a long distance call!
for those stuck with HIGH/LOW (on or off) outputs, make sure you use an analog output (pins with a tilde), stumped me for a bit until i remembered Paul mentioned something about it (i watch the video to the end before attempting the project on my own).
You are a great teacher ! Specially because your not just teaching us like : 'do this and do that'. Your explanation of how things work and why it does do are the key value, at least for me. Thank you ! Greetings from Serbia !
I'm 72 and did a little programming in my late teens early 20's. The language has changed principles of programming exactly the same. Well done for clarity of explanation. Have also completed your homework
I always wanted to use my GREEN LED. Thanks Paul!
Hi Paul! I am an undergraduate student pursuing a Ph.D. degree in biomedical engineering and your videos have helped me a ton! I follow along with my own kit and really enjoy your lessons. They have taught me a lot! Thanks for being awesome and enjoy your coffee (no sugar)!
Thank you for your kind words. Best of luck in your education and career.
Paul, old guy new at this loving it, and YES doing all the homework .
I am here and learning, at 73 I am starting over with a train layout and will be using Arduino to control functions on the layout: turnouts, signals, lighting, and later sound effects. Thanks for these lessons, I am learning many things. Last programming I did was FORTRAN.
Now, because of the COV-19 we have to stay at home, so I have a lot ot time to learn from you and I really enjoy to play with these items :)
My son just finished taking this lesson, he now understands one application of the equation of a line and slip of a line.
Thank you 🙏🏻
Haven't only watched this series, since you're a great guy and teacher wether it is i WILL watch it because it is indeed fun and great
Paul, I appreciate your down-to-earth method of teaching. I am 78 and a retired manufacturing engineer. I worked with PLCs, but I love learning the Arduino. I am working on a program and schematic for a PID temperature controller for a pressure fryer with adjustable setpoint and LCD display, working from a K thermocouple and Max6675. My problem at this time is trying to trigger two SSRs with a PCM output from the Arduino. Thanks again.
Flowed along just well. I like the live mistakes, teaches me more then just do this and that's that. With the mistakes it really shows why it has to be done certain ways.
I do the Homework and also try to throw something more at it sometimes. This time I added second Pot that delayed(pulsed). Used the formula to put the pulse range to my desire, settled with delayvalue= (75./1023.)*potval2 making 5v aka 255=100ms
While first Pot dimmed dimmed them.
i actually studied computer engineering 30 years ago but never practiced it. your series are simply awesome, good refresher, at least for me.
i just got the kit about a week ago and i'm going through these lessons. a few dozen more and i should catch up to the current one.
Some feedback.
I follow all the lessons and do the projects at the same time. So far i haven't had any problems understanding the lessons, but this time i found it a little more complicated since im not so good at maths. I'm 53yrs old so it was a while since i went to school and this lesson was very good to refresh the memory. I find the programming easy to understand and you are very good at teaching.
Even though im not so good at english i find it quite easy to understand your explanations and you talk with words that is easy to understand even for someone that dosen't speak english very often.
Thank You for your work with these videos. They are most appreciated. Regards from Sweden
As always, good job on the math connection to reality.
Dear Paul.... I am elect.eng (75 years old) with 40 years in South Africa, and that is the first time a lecture touch my hearth. I try before many lecturers , but the way you produce the modules is fantastic. Your english (I come from Argentina) is excellent and you talk slowly and clear. I am drinking ice coffe all day!!!!... I follow you to the end!!!!... Buena Suerte!!!. Jorge in Mandeland (land of Nelson Mandela)
"Hook a brother" lmao every time it makes me laugh. Legendary teacher!
I love video
One of the things I enjoy the most, is Paul gets excited at the exact same time as I do when something works. I think no matter the complexity, when you are making something and it finally works as intended, that is one of the best feelings.
I’m playing along. And doing the home work.
I like this lesson. It made me think through the steps and the reasoning behind entering the commands instead of just coping you. I would pause, think it out, then see how I did. It's all coming together! I'm spending my first hour at work doing a lesson, with a project in mind as the end goal. I haven't felt this engaged in years. Thanks a bunch Paul.
Excellent!
This is the only non-mandatory homework that I participate in
The best channel to study electronics , perfection in every video .
"Today you are going to be allowed to use a green LED"
Previously, on new and Improved Arduino Tutorial: "for assignment: use green and yellow LED"
He's just assuming noone did their homework. (we did)
Yup thats true
I watch these multiple videos and then bfr going to sleep to honor the efforts and the man I try them all.
you saw salvation if i am right
I’m a rebel, I used 4 different colours for the binary counter.
@@markharrisllb I am also an edgy rebel, I didnt have yellow LED's so I used red green and blue. I know I know, I like to watch the world burn!
These lectures are so helpful. I do the homework, follow along. I'm a 20 year old nuclear engineering student at MIT and I'm trying to learn programming and Arduino. This is like baby's first electrical engineering and I love it. Thank you!
I'm 11 but I feel like I have the knowledge of an adult

My LED kept getting brighter and brighter unto the perfect day😂. You're a great teacher. Three years and you're still not talking to a wall.
Wow, thank you!
Oh man ... don't think for a second that you're talking to a wall. I mimic every step and take every possible note. Thanks again!
I was developing software for the DOD (USAF) in 1961 and have been in various Information System Engineering and Management positions ever since, at least until my retirement a few year ago. I'm an octogenarian with a physics and math education, so it is the Arduino I'm learning here. Appreciate your efforts, even if a few things seem old hat - heck I'm probably considered old hat. Thanks.
I did the homework in tutorial 13 and before I watched this one, I tried getting the LEDs to dim as I turned the potentiometer. With A LOT of trial and error I kind of got it to do something. This is fun!
Always watch from the beginning to the end without even skipping. You are the greatest teacher i ever had. Thank you sir
hello from Brazil, i am industrial electrician.
I've staterd playing with arduino a week ago and i discover that learning English was one of the best thing that i did. it not only helps me with the coding, but also gives me the ability to understand amazing contents like this one in the video.
Thanks for sharing
I'm still watching these videos. I'm learning quite a bit. I've had Arduino kits before, but I'm learning so much more in these videos instead of just following projects. I did the homework project and was successful!
P.S. I don't drink coffee at all.
The lessons are great, thanks Paul! I'm a 66 yr old retired mechanical engineer, and really enjoy learning about Arduino circuits and programs. I've been building and coding every project as you narrate. Lots of fun and very educational!
Great to hear!
I'm 59 years old and when you said linear equation I was going to quit too...but I agree with Suhaan, you explain well, I continue to learn! Thank you.
100% Not talking to a wall! I absolutely loving this series of lessons! I follow along with every lesson and take notes throughout. I'll be real, when I got to the first lesson about potentiometers I thought I was all smart and tried hooking up a red led to the output pin... Yeah learned a lesson there haha! Did it twice just to be sure. Glad I made it to this lesson, this really clicked a few puzzle piece in place and I understand better why my early attempt failed and how most electronics actually work. I really appreciate the slow approach to painting the beautiful landscape of micro electronic engineering!! As some others have said, you're like the Bob Ross of electronics!
You are not talking to the wall. You are talking to a group of experimenters who are learning more from your videos than we learned in school. Thank You for your dedication.
I struggled with this concept for a while, but now it is sinking in how important it is to understand the math along with the practical work. These calculations that you have explained so well are now clear to me, thanks to the clarity and patient manor in which you teach. Cheers, Paul !
Definitely, not talking to a wall. Your lessons are amazing. Doing homework helps to retain the concepts. Thank you for adding the math. I included the math in the code as comments, so I can remember when it all came from when I see the program months later. Keep the excellent work.
You are not talking to a wall professor! Seriously, this is the best series/book/university course Ive come across in 20 years as an engineer. I cant thank you enough.
Paul, I can assure you are not talking to a wall. I recently bought an Ardurio kit for my grand son and while we were working together with it, I bought one for myself! Why should he have all the fun?. :) I stumbled onto your tutorial videos and currently am working through them. I have finished 14 of them so far and plan to go through all of them. You have done an exemplary job in demonstrating how to setup circuits and describe how to program. I worked as a tech instructor ~40 years ago using HeathKit trainers and 6800 processors. This is probably much better than what we did with those back then. Thank you for providing this content on UA-cam. It is a blessing.
Excellent!
No sir, you are not talking to a wall.
We actually do follow along and it is so much fun when I am able to do this project on my own.
All thanks to you.
I hope everyone gets a teacher like you to guide them with whatever they are trying to learn.
So nice of you
I'm 16, from the UK and a friend recommended me to watch your vids. Now I'm hooked!
Thank you Paul, I have been watching your tutorials for years, after a break I went back to study them once again as people always go back to reading their favorite books. I always enjoy your tutorials and find them very, very useful for my work. Thank you once again for sharing your knowledge with us.
Excellent
I am just on a marathon to learn Arduino.. And I began last night. I felt so satisfied with my first project. Many thanks for your help, sir!
Yes, I am playing along at home and having a great time. Two weeks ago I didn't know anything about Arduino. Now I can write programs and make projects.
Thanks very much for your time and effort.
5 years later and you're still not talking to a wall, Thank you so much.
I listen to every word and do everything you do on the screen. It's tedious at times but I like the careful way that catches all the problems. Great teaching style.
I ran into the same connection issue as you did on this project. I learned in the last lesson that the potentiometer seems to be the weak link in this connection. In both instances, I had to apply quite a bit of pressure on the potentiometer to the breadboard in order for the connection be reliable. Thank you so much for the lessons... and yes, I listened to the whole video. Also, you have about 5 new viewers that I have shared with... I'll keep 'em coming.
thank you so much Paul. I am really enjoying you videos and yes i do watch them all the way through and also build
every project with you . Keep up this most excellent series I'm 63 and loving it
Found this in 2022. Watching your videos from Minnesota. I watched it all and I've been following along. Thanks for the series! :)
Paul,
Just want to say how much of a breath of fresh air it is to have a teacher actually break down everything and then build it up. Not just a do this, do that, you now have this.
So far, the amount of stuff I have learnt in 14 lessons and retained is beyond what any other kit/class/video series has taught me and for that I am thankful.
Before you finished I added a couple if statements to try to incorporate the last lesson with this one. I had a if(ledVal == 255){ Serial.println("The LED is set at maximum brightness";} And vice versa for it being off. To understand how those things work after just learning about it makes me realize how well you teach things.
Thanks for the great series, and I look forward to learning more!
2 years later and your videos are still just as relevant!
you have helped me go from zero understanding to having the ability to make my own projects!
more to come!
I managed to connect two LEDs and use the single pot to control opposing brightness. I noticed that as one LED got brighter and the other got dimmer, it didn't do so in a linear manner. So, I set some arbitrary thresholds using what I learned in your 'if' lesson, and changed the PWM value by a factor (which could be adjusted as a variable, of course) so that the brightness of the opposing LEDs changed in a more proportionate manner.
In the space of two weeks you've helped me come a long way already, and I'm enjoying the mix of theory, practice and homework. See you in Lesson 15.
You are not talking to the wall Sir, I am totally working through these projects and following along as closely as I can. this one threw me for a loop because when I went to look at the serial monitor, I was getting crazy voltages. I went back over all of the void loop entries several times and I was just about to hang it up for the night when I looked up to the very top and realized I hadn't set the potPin value to A1. Once I corrected that, everything worked perfectly.
Thank you for providing such an interesting instructional series.
Hi Paul, I'm pushing 60 and just bought my first Arduino. I didn't even know what that was a few months ago! I follow the tutorials in full and do my homework before watching the next. Incredible series.
Late to the party? But I like to pause the video before you start coding, or even wiring, and then I do it myself before being shown the solution. And 99.9% of the time, I'm the one going BOOM! Nailed it!
Thank you so much for the well made lessons. Baby steps explained this way is great to learn and retain all that information.
Yes someone is listening and yes someone is following along. I have a Dr. Duino kit from a HAM radio friend. Thank you.
NOT TALKING TO WALLS ..
I LOVE YOUR WAY OF TEACHING
YOU ARE SOOOOOO GREAT
I CANNOT STOP WATCHING YOUR LESSONS..
💚💚💚
My name is Welvaert Eddy from Belgium.
The lessons are very educational and clearly explained.
Also afterwards for the assignments to do with great success if I say so myself. One thing don't constantly tinker with your Arduino to see if it is straight, usually it is straight.
Mr. McWhortor, I wrote a program of my own to dim three led's that I am using on my temperature/humidly meter, using the DHT-11. As I rotated the pot, it would reach full brightness and the go out and then as I continued to turn the pot, it would keep doing this. I couldn't figure out why. I opened the serial Monitor and saw that I was writing from 0 to 1023, just as you said not to do! I forgot to find the slope of the line and write the equation! Man, you are good. I spent a lot of time trying to figure this out then, I remembered your lesson 14 and, boom! The circuit is working. All I have to do now is incorporate it into my program for my temp/humidity meter. I did work it out myself but, I admit I didn't remember how to write the equation into the Arduino sketch. Thanks sir for all your lessons. I'm a bit slow at 76 years young but, I eventually get it! Ha ha!
another great video! I've found if i don't do a module or two every day i begin to forget some syntax or certain key points.
So I've gone back today with a pencil and paper and written proper notes so i can review and reference from when trying to do the projects on my own. this has helped tremendously with the formulas and doing the math.
As a young kid i often slept through my math classes since i didn't see any reason to bother memorizing it at the time, but now after seeing some practical application, ive found new reason to be interested in learning it. which makes the whole learning process easier and more successful.
Learning because you want to and not because you're told you have to, makes all the difference. i find myself after these videos spending additional time doing extra homework using external sources like khan academy just to get more practice using the equations presented in these videos to solve other problems.
if someone would have told highschool me that i would be doing math in my spare time because i wanted to, i would have laughed at you lol.
You’re not talking to a wall but across time. I bought another Adruino and the the tutorials were so bad I looked for help and found it with you. Bought the most complete starter kit and am so happy I did. Thank you
Paul, I am enjoying working through each of these tutorials and the extra assignments. I have been adding comments in the code to self-document as I was taught in Computer Science classes beginning in 1972 into the early 80's and saving each sketch, numbered according to each tutorial's number.
klrwhizkid I am doing the same with the documenting and saving. Also using commenting to keep older versions with the newer version on the same sketch when there is a change to the code.
Great videos for learning Arduino. A really good step for step teaching how to do including some calculations and bringing the whole stuff together in a practical way. In the 80's I did some BASIC programming and Z-80 assembly so this Arduino uP is very easy and powerful in interfacing. Apart from the super cheap materials these days. The way you can bring over this knowledge is already amazing and many teachers can learn from your method. Greeting from the Netherlands, Robert!
Glad it was helpful!
You are NOT talking to a wall. Paul, I did indeed watch the whole video. I am 80, but feel much younger. Math was not my forte in school. You make learning difficult Arduino tutorials so much easier to understand and grasp. Thank you and please keep making these great videos.
I am watching your vids every evening! I have ZERO electronics experience and so far i been able to keep up and successfully complete the lessons up to #14. Im also a ham radio operator and that has sparked this desire to learn more in this area. Thanks for what you do!
