The 555 has been my favorite classic IC for over 20 years. I really enjoyed this video and learned some new things about this awesome, long lived chip.
Your videos are amazing ! So much information, you're going straight to the point without any detours. The information is tightly packed and the whole subject is covered quickly and efficiently. If looking for one specific information, I can watch 4 or 5 videos in what feels like no time and I'm very likely to find what I'm looking for. As an other non native english speaker (i'm french) I am very happy to be able to use english as a way to communicate with somebody that eager to make the world a smarter place.
Another great video, Great Scott! My advice is to keep up your high tempo, despite the complaints that you're going too fast. I'm a beginner, and you're "too quick" for me too, but that's good motivation to learn more so I can eventually keep up... and your videos are never boring! In all the language classes I've taken there is always a student who complains the teacher is speaking too quickly. One teacher responded "No. You're listening too slowly." That's right on the money!
You do insane practical experiments. I am afraid while watching your wiring connections, setting up electronic components. Your intellect is really high. 👍🏻🇮🇳
Not like it .. love it. Been far too long since I've seen someone explain basic electronics so concisely and clearly amongst all the noisemakers. Here's a thumbs up from one professional to another.
Did that, as pathetic as it may sound to someone who actualy understands electronics, but there are to many elements unkown to me. I'd need to sotp the vid, go investigate what is that flipflop for instance, then come back and lsiten to the rest of it.. Ijm just too dumb.
I agree with both of you. that is the beauty of youtube and having so many people talk about the same thing. you can jump in the deep end and not understand lots of things and you can go and listen to a noob which both are very usefull, when your goal is just to learn. just use your intelligence. its like if you speak to the top brain surgeon you probably wont understand hardy anything but talk to the beginner he will probably spend 10 mins talking about keeping tools clean. where the pro never mentioned it once but its fundamental. But use ur intelligence and you can learn key points very fast.
This is how Electronics must be thought! I'm a Electronics Graduate yet never knew how 555 came. Also many times I had used the formula 1/3Vcc or 2/3Vcc and am able to relate due to your video.., Great effort and thanks for that...
Simple and super useful! Thanks! Nice that you draw internal "logic" scheme and upon that explained how 555 works! Like your "way of thinkg" and step by step explanation, where one thing is consequence of another. Great job!
I highly appreciate the fundamentals lesson. I'm still so new to hobby electronics, it is nice to see where people with more knowledge throw in diodes and other components.
For once, I actually fully understand a GreatScott! video :D Edit: Not to say your videos are confusing, but you explained the 555 in such a fantastic way.
I love you for this video.. you just gave me the answer to a problem I was trying to solve with my home automation system.. sincerely, thank you for all of your videos.
I don't understand anything. Your explanation was the best I've seen so far all over UA-cam and College, but it reflects a deep lack of electronic technical foundation in me haha. However, you deserve thumbs up. Congratulations my friend.
Can't remember how I came across your channel, but watching your videos has rekindled my childhood interest in electronics! Have always wanted an oscilloscope - messing around with 555's give me a reason to get one! ;) Edit: Subbed. :)
What a coincidence i was messing arround with one NE555 just now. And this video helped me to solve a question, its like im asked a question and GreatScott! Created a video to reply. Thank you a lot for the video and keep up with the good work.
The topic is very old, but the explanations as usual are great. I especially love your hand-made diagrams that tell us how we should think about electronics, how it works in detail. Great job Congratulations
It's my first comment on any youtube video and I just love watching you video I just started watching your video from last few week in starting I use to watch any random video of your then it just blood up my mind because I am not from technical background but I like it so I watched all your 26 electronic basic video and it helped me a bit knowing what you are doing and after seeing your video I too want to make things for my self and I will start from making a bench top power supply from atx and thanks for inspiring me
Hey bro, I am from India .I always looks for this day at 7 to 9 pm (Indian local time) for your videos. You explain every basics of electronics so nicely that I am going crazy for diy stuffs. Can you make more videos for us ? Thanks A Lots for your Videos. hats off bro !
I am happy that I can pull off one video every week. It is definitely not easy and producing more videos in one week is impossible for me. But feel free to support me through Patreon. Maybe I can hire an assistant one day.
Well, I feel you're better than most of the Electronics Engineer I've seen. Anyway, I will be starting BSc in Electronics Engineering very soon. Hope your videos will be helpful in the future as well. Thanks!!!
I believe that this is explained well and simply, but me small brain could not grasp most. I have bookmarked this video and will be back later when I understand more. Thanks Scott for the inspiring video :)
excellent video. I"m learning and relearning a LOT with the Great Scott Videos. I share these with my work mates often. we work at FoMoCo. thank you Mr. Great Scott!!
thank you. your videos are always creative and informative.keep it up. By the way, i got to design Schmitt Trigger in my electronics lab last semester ,and your videos really helped me
I once met a guy in a pub and he asked me what my favorite IC was, -- Why would asked ? He said "well a love the 555" and I replied " a 556 and I'm nipping outside for a joint"
Vielen Dank, die analogen Chips aind mir noch immer oft ein Rätsel ... die Namensgebung war eine sehr interessante News. Und ... sehr gute Zeichnungen!
I find that just using an Arduino board (or any micro-controller with PWM) is easier because 1; you don't need any extra components other than a potentiometer and the load and 2; I find writing a few lines of code easier than hooking up components in a way that I only somewhat (even after watching this great video and others) understand.
There are applications when using an MC is a waste. Sometimes it just comes in handy to know how to create some simple circuits without programming anything.
U r Simply great man... Keep Doing for us like this.. may be many of us would not be able to support patron campaign.. as we also dont have such financial support nw but we gave our blessing to u...
Nice! So it is possble to make a circuit with stable PWM frequency, using just one 555 - another trick is to use an external oscillator with set frequency and let it trigger the the 555 in monostable mode and use the control voltage pin to adjust duty cycle. For most applications it probably doesn't matter if frequency drifts a little. I have a 9 kW furnace that I control with the simple 2 diode circuit - at high duty cycles, the frequency drops a little, but that's just good because the transistor runs a little cooler during high load (switching losses goes down with frequency), while the ripple current is still low at around 50% duty cycles (where that is at it's at maximum)
The 555 has been my favorite classic IC for over 20 years. I really enjoyed this video and learned some new things about this awesome, long lived chip.
pls suggest if there is really any way to generate good square wave using NE555/NA555 IC? as I only have that available with me
@@kritikagupta8585he showed you how to do it in the video with the astable cmos 555 timer 😭
I've been using 555 with no idea why we connected it in such configurations .. when u got to the deeper level .. everything is clearer .. thanks boss
you have very neat handwriting Scott
He does
Yeah, and English isn’t even his first language
Your channel is top notch. Gives guidance to a beginner but have enough details if one wants a geeky deep dive.
i thougth i knew 555s, now im looking at the ceiling thinking wtf am i doing with my life
Glad I’m not the only one
ua-cam.com/video/EGmreVQ-yNM/v-deo.html
This is the best explanation of 555 timer IC I found
You aren't the only one mate.
The 555 was my favorite chip to use in high school back in the 80s. Boy I feel old.
i was just telling someone i am about 3 decades late with this hobby of making circuits with a 555

Best 555 timer explenation video that i ever seen. Thanks from Poland for your work.
gotta love whenever I wanna do a project with a specific chip and cant grasp it you come in and clear it all up. keep up the great content!
The 555 changed my life. First IC I ever worked with in electronics class in high school.
You're one of the most interesting youtubers ever!
Thanks
Great versatile chip that's been around over 40 years. Thanks for the easy to follow informative u tube vidios.
the best, most complete, and consise description of 555 timmer! haden't noticed different versions of timmer either. thank-you.
You do insane practical experiments.
I am afraid while watching your wiring connections, setting up electronic components.
Your intellect is really high. 👍🏻🇮🇳
Not like it .. love it. Been far too long since I've seen someone explain basic electronics so concisely and clearly amongst all the noisemakers. Here's a thumbs up from one professional to another.
my favorite youtuber looking at my favorite IC, its a happy day
I didn't think there was much point in *another* video on the 555, but yours is definitely worthwhile. Well done!
Best 555 video on UA-cam! Thanks GreatScott.
Finally, an actual video explaining what is the 555 like inside, thanks a lot
Im affraid that for half fo us this is way too hard to catch on, all too quick D:
Did that, as pathetic as it may sound to someone who actualy understands electronics, but there are to many elements unkown to me. I'd need to sotp the vid, go investigate what is that flipflop for instance, then come back and lsiten to the rest of it.. Ijm just too dumb.
iceberg789 that's right xD 14 hours of study compressed in only one video. for me at least xD great scot is indeed great xD have a nice day!
I agree with both of you. that is the beauty of youtube and having so many people talk about the same thing. you can jump in the deep end and not understand lots of things and you can go and listen to a noob which both are very usefull, when your goal is just to learn. just use your intelligence.

But use ur intelligence and you can learn key points very fast.
it would be unfair to ask the top brain surgeon to cover everything from the most basic and you would miss out on the cool stuff he really knows.
For me it makes sense but I'm already in school for electronics. I think this is who it's primarily for.
Can't believe the 555 is still around. Nice intro to the inner workings.
Given how verstaile the 555 is, i doubt it will ever go away. I've even seen it used as a Class-D amplifier!
This is how Electronics must be thought! I'm a Electronics Graduate yet never knew how 555 came. Also many times I had used the formula 1/3Vcc or 2/3Vcc and am able to relate due to your video.., Great effort and thanks for that...
Am I the only 1 watching and not understanding almost anything, but still likes the video anyway?
*****
Well, that's unfortunate... nobody else but me likes Scott's video...
You're not alone sir...
Not at all
watch codenmore's video, its amazing
He did hurry it up a bit...
Simple and super useful! Thanks! Nice that you draw internal "logic" scheme and upon that explained how 555 works! Like your "way of thinkg" and step by step explanation, where one thing is consequence of another. Great job!
Your drawings are immaculate!!! I love your channel. I am an engineer and I love your projects and breakdowns of circuits.
my first greatscott video from 2016 😄
This has to be one of the best electronics videos I've ever seen. My sincere thanks to you
I LOVE THIS! it's going in my recipe book of very useful electronics chunks. EVERYBODY got time for a pwm generator!!
it was superb, every week we have a nice surprise here!! Thanks again.
You're welcome
I highly appreciate the fundamentals lesson. I'm still so new to hobby electronics, it is nice to see where people with more knowledge throw in diodes and other components.
For once, I actually fully understand a GreatScott! video :D
Edit: Not to say your videos are confusing, but you explained the 555 in such a fantastic way.
It was well explained, but it still went over my head. I have a lot to learn!
I had watched this vidio 4 time and at my 4th attempt I finally got the idea 😅
Great Scott, that's the most absolutely fantastic explanation of my favourite IC, its so crystal clear now, thank you
I love you for this video.. you just gave me the answer to a problem I was trying to solve with my home automation system.. sincerely, thank you for all of your videos.
I wish you would have posted this video a day earlier. I had a 555 question in my exam 😑😅
iceberg789 lol. I hope not. Results aren't announced yet. 😅
how to make HAND GRENADE at home............WATCH ON MY CHANNEL
Better hope the grenade fuse is made with a 555 timer with a 10 second delay
subcribe to muh channil and i'll post a video about how to build an anti-matter bomb.
tested. it works i'm commenting from hell right now. ...connnection here is shitty though iceberg789
Your Courses are really useful! love from algeria
I don't understand anything. Your explanation was the best I've seen so far all over UA-cam and College, but it reflects a deep lack of electronic technical foundation in me haha. However, you deserve thumbs up. Congratulations my friend.

Funny how I always can learn from a 555. I really like your explanation with the 555 timer. A big thumbs up for you. Thanks
Your are a good teacher, you deliver a good explanation
Thank you so very much. Every one of your videos that I have watched has been helpful.
what ??? You have made me completely understand a timmer IC unit in integrated circuits subject ....thank you so much...
Very good video!!! Congratulations from Bulgaria!!I watch your vids from about a year and Im pretty impressed!!!I hope you never stop!!
Thanks mate :-)
Best 555 tutorial I've seen!
Beautifully clear diagrams and editing work.
What a coincidence i was messing arround with one NE555 just now.
And this video helped me to solve a question, its like im asked a question and GreatScott! Created a video to reply.
Thank you a lot for the video and keep up with the good work.

Well, I feel you're better than most of the Electronics Engineer I've seen. Anyway, I will be starting BSc in Electronics Engineering very soon. Hope your videos will be helpful in the future as well. Thanks!!!
Did you finish your degree?
thanks for this video!! tomorrow is my exam and i was in need of this!!
I believe that this is explained well and simply, but me small brain could not grasp most. I have bookmarked this video and will be back later when I understand more. Thanks Scott for the inspiring video :)
Oh my god man, those hand drawn diagrams are so smooth!
excellent video. I"m learning and relearning a LOT with the Great Scott Videos. I share these with my work mates often. we work at FoMoCo. thank you Mr. Great Scott!!
liked how you told us about the limitation of the 555 timer for PWM signal : marked at 6:14 time in the vid That was great info and problem solving.
thank you. your videos are always creative and informative.keep it up. By the way, i got to design Schmitt Trigger in my electronics lab last semester ,and your videos really helped me
Perfect timing for me. I just started planning some experiments with a 555. Thanks !
Definitely a work horse in the electronics world.
Your left hand write is like gold
I've been dying for this since time began!
I'm just speachless..... amazing stuff!
The best tutorial I could find for 555 timer!!
I once met a guy in a pub and he asked me what my favorite IC was, -- Why would asked ? He said "well a love the 555" and I replied " a 556 and I'm nipping outside for a joint"
Vielen Dank, die analogen Chips aind mir noch immer oft ein Rätsel ... die Namensgebung war eine sehr interessante News. Und ... sehr gute Zeichnungen!
Great vid,This is the first explanation video that didn't go to fast for stupid me.
Türkçe altyazı için çok teşekkürler.
Thank you very much for Turkish translation and your effort, great!

I never really got what the big deal was with 555 timers until I watched this video. that pulse wave looked so sick
U r Simply great man... Keep Doing for us like this.. may be many of us would not be able to support patron campaign.. as we also dont have such financial support nw but we gave our blessing to u...
As Per usual, Scott. Quality video and good explanation. Keep it up, sir. You've more than earned every sub.
true
Always good quality and frequent videos
well done great. i'm from Mozambique and i watch all you videos.
I was waiting for this!

Nice profile pic hhhh
*explains all details* and now you know all the basics :D thanks for the excellent video!
Great video. Just what new to electronics people need. Keep up the good work.
Sir all of your video help me to my projects.
and i learn all of this because of you than the school thanks
I built all these circuits 25 years ago! 555 stands the test of time. I wonder how many have actually been made
I'd really like a series of videos going over the top 10 ICs you consider most useful like the 555.
Amazing teaching. thank very much. you are intelligent teacher
Thank you Scott, your videos are short and super clear. Keep making more. 🤝
Nice fundamentals lesson, Scott! :D
Thanks
GreatScott!
wtf?^^^^
How is it important for this video?
+GreatScott! Pls Make a video on inverter ( may be 5 level )
thank u very much soon i have project to make stun gun with 555 in school so this will help me, keep making videos ur the best!
A good summary of the 555 timer IC. Thank you !
Really helpful! Thanks for taking the time to explain how the timer works so well in this video.
It is much easier to understand your videos with a reference book at my side
just in time. I have it included in my upcoming exam . Thanks alot.
Best basics video ever saw
One day I’ll be doing these vids. Thanks @Greatscott For Inspiration.
Really superb videos u r videos are amazing and u start all from scratch ....nice work man...keep it up.....
Good to know about the c-mos version of the 555 for PWM circuits. P.s. one of my favourite channels,, always full of info...
Great explaination thank you you deserve more likes
Nice!
So it is possble to make a circuit with stable PWM frequency, using just one 555 - another trick is to use an external oscillator with set frequency and let it trigger the the 555 in monostable mode and use the control voltage pin to adjust duty cycle.

Excellent summary as a refresher. Thank you!
Excellent video !!! Nobody does it as well as you !!! Thanks !! ;) ;)
Donald Filbert
Oh man thank you I needed this video, about to do a project which needs dimmable LED's
This is what call.... PASSION!
Great video! yes you speak fast but I can always pause and replay the parts I didn't understand the first time. :) :)
Thank you for this video...yesterday i just learned 555 ic timer...and greatful you had the vid😄
Einzigartig gut erklärt und dargestellt!
