You can pick up the neat jumper wires I showed in the video here:

You guys can help me out over at Patreon, and that will help me keep my gear updated, and help me keep this quality content coming:

In this video I introduce you to the concept of analog voltages on the Arduino Uno R4 Serial Monitor. I show how to use the analogWrite command to simulate analog signals. Enjoy!

I watched Paul again. I was not a good listener. I only did the ramp up and missed the ramp down portion in the HW. My Mom saved a kindergarten assignment that had bold red letters "Did you listen to the assignment?" She saved it for years! Old habits persist.
I was the same way,
This one is a great class since it requires additional logic. I previously did some python classes and remembered the use of if statements. I don't yet know the code for arduino so I needed a little internet search help to figure it out. I appreciate the time you take to make these videos, teaching others is a gift you are giving to the world so one day we may return the favour.
Yes, this another Great introduction to analog write!
Sorry I missed last weeks class and the one this morning. I have been tied up with Doctor appointments.
Thanks Prof Paul. Another great tutorial. I enjoyed the Homework. It's amazing how much I've forgotten since your last Arduino course I did with you a few months back. This course is a really vital refresher and, like you, I keep getting my Python coding mixed up with the Arduino stuff. I'm enjoying redoing a lot of the things we did last time because I have forgotten so much, so I am pleasantly working my way back to a semblance of understanding of this "basic" stuff in readiness for the more advanced and new R4 WiFi tutorials. Is there any chance we can actually do some WiFi related tutorials, that would be really stunning?
Analog volts! Thanks Paul
You should make a download PDF of each sketch to go with your videos, then we could build a Notebook of code when we need to refer back to something!
Thank you ❤
Great job Paul!
Thanks Paul
Don't drink coffee but I do have a nice tall glass of ice cold tea. Straight up, black tea, poured over ice. No sugar. No sweeteners. None needed.
Unsweetened tea definitely on the approved beverage list for the channel. I do love iced tea as well, sometimes with a few mint leaves.
Thank you sir... Is there somewhere we can clip the code into my IDE?
Was playing with RGB and forgot to put pinMode(bLedPin.OUTPUT); in setup. Blue LED still came on so I remove pinMode for both rLed and gLed and they still worked also. I guess with analog pins defined as variables above void setup I don't need to pinMode statements in void setup. Is there a reason I should do it for good coding practices?
Hi Paul! I have a question: What difference is between opening the bare minimum example sketch, and just open a new sketch?
Hey paul thanks for the tutorials, could I ask what specifications does your computer have?
A bit of a weird question but can I use your Raspberry Pi Pico lessons with my esp32 I am no beginner I'm just asking is most of the programs compatible with the esp32? Love the lessons
I ran into your livestream on DAC quite by accident on March 31, 2024. It ran live on the 15th. Where do you announce these supplemental lessons?
When you subsribe to the channel click the bell and ask to get all notifications.
@@paulmcwhorter The bell is, and has been, activated. Maybe I did not notice the notification. Any idea when the next one is coming out?
Pardon the interruption. Is there any kind of community discussion channel to share comments about Arduino, the class, and learning in general? Something like discord would be great. Paul has a section called Community, but it has not been used in years.
I am asking the question here in lesson 10. The lessons are NOT the right place for general discussions and the Arduino forum is massive. For example, today I have been learning about Arduino memory mapping. For the Nano memory begins with 32 registers from location 0x0000 - 0x001F. Of importance to me for the Nano is that SRAM runs from 0x0100 - 0x08FF. None of this would be of importance to a beginner who is trying to get his head around int and float. But, it does interest me. Any ideas?
👍
Sir, can u upload video tutorial about emonLibCM?
Is there a way to complete the homework assignment using just the elements that have been taught up to this point? I see a lot of completed homework assignments using commands like "constrain" and "for" which up to this point he has not covered.
Yes you can do it with just what I have taught so far.
@@paulmcwhorter Thank you for the quick response. I see how to do it now. I was overthinking the solution. These lessons are wonderful and I am so happy you took the time to make them.

I'm on a r3😊
I'm onto it this week. Homework done: ua-cam.com/video/6ojTW74dB_E/v-deo.html

2nd try at adding my Homework. ua-cam.com/video/YpMOtsofg_U/v-deo.html
My HW. ua-cam.com/video/BwSFeFFXpj0/v-deo.html Hope fully I set this up so comments are allowed. Thanks Paul.

Here's the (6th) notification for my lesson 9 homework - no link, no description, nothing to make you know who delete it.
I'm now editing it with the link: ua-cam.com/video/xzjLXp6wG90/v-deo.html
Charlotte, I had the same problem I had to post my comment 4 times! it kept disappearing after I posted it to the web site, all I can say is don't give up.
Here is my homework for Lesson 10: ua-cam.com/video/F4W3iPCLl7Q/v-deo.html. Thanks for the lessons Paul.

Lesson 10 completed and video uploaded.

Very nice. I learn a lot from watching your videos.
@@richardsstark9825 That very kind of you, Richard. I actually learn a lot from rewatching my videos as my memory is so bad🙃Supposedly Einstein had a bad memory too.
Hello Paul, this is my third attempt at posting my homework assignment. I don't understand why it disappears

Martin, that often happens to me too. I have tried, without success, to track it down. That being said, if you persist, as you have done here, it will stick. When I type my comments, I hold a copy on file so if it fails, I don't have to retype the whole thing. Hope this helps. Bob

I noticed that the same happens even on non PWM pins, why is that??
Thanks

Homework done! Thanks a lot! (i'll work in improving my videos when I have a little of time to do that). ua-cam.com/users/shortsBnth_X-vpYE?feature=shared
Please post the videos as normal youtube video, not a short. Shorts are harder to see, and cant leave comments.
@@paulmcwhorter I'm new in this and I don't know how to do that yet, but I'll do my best to do it asap.

Thanks Ed, I really appreciate that, it means a lot to me!
