I have been binging on circuit design videos and blogs, and this is downright the best video i've seen. So clear, explaining every aspect in a very understandable manner, just awesome.
out freakin standing! I am just teaching myself electronics and at 70 it is harder than I thought.. But your videos break it down to total understanding for me.. thanks little brother.. you da man!
I'm studying Computer Engineering, this video was really needed for me to understand how to go from theory to practice. Also, a bit funny how I looked up the 555 just a few hours before you posted this.
Outstanding class. I did keep re-running several parts of the video, and putting the speed down to 0.75x to get a hang of it. And now I know how a 555 timer works. Thanks for this. For a backstory, I am new to electronics and have a good inclination towards repairing my stuff. When I went to learn from a ‘master’, the first thing he asked me was ‘do you know how a 555 timer works?’. I told him no. He sent me away, telling me that he will take me in once I figure out what makes a 555 timer a 555 timer. At least the basics. And then he will take me in. He was like ‘its the heart of concepts of everything electronics’. So much more to learn, but this is a really good place. I already subbed to a course on Udemy, but this has done a better job at giving me an understanding. If you read this far, thanks for being patient with my rant, and I hope you have a great day ahead. :)
Thanks for doing these series !! Being very new to electronics , I don't fully understand it, but thanks to your channel I am slowly piecing it together.
man thayt was intense. i wrote all of it down pausing it as u went along and i must say i learned alot here i am gonna build mine from scratch seeing how im just starting up and i gotta find a motor and all that so im statring all this just to power a huge stereo im trying to build from scratch this is a great journey and i love every min of it learning all i can thanks again.
Your bread board is so clean. I'm going to start working to keep my work as tidy. I like how all your grounds are on one side and all your hots are on the other, makes it very easy to follow.
I really want to just archive all your videos. I don't want to see these disappear one day, as I want to keep this knowledge out there for everyone to have access to.
My senior project, I did it with a PLL control circuit 30 some yrs ago. I also did a digital version with 8051 microcontroller as comparison. Enough to earned me a degree. Bring back good memories seeing this.
Great work. I have made this circuit almost 5 months ago. It really work perfectly. But i saw your channel first time today. You provided all information about it.
I subscribed a lot of channels like your channel but i wanna thank you so much because you are explaing how electronic components which is using on circuit board. This make me happy and i got it how it works when you simulated. I am interesting in board designing but my knowladge is poor. Thanks a lot.
Very cool! Great animation, explanation, 3D models, and even made a dedicated printed circuit board. My nephew is going to dig this when we make our breadboard circuit officially on a PCB.
Great explanation of a 555 timer chip function. Those little giants are use in so many circuits. Got to be the best little chip ever designed... Thumbs Up!
At 5:02 you said you add a fly back diode and on the image it says flywheel diode. I love your content you teach all the little details, keep up the great work!
Rarely have I seen such a well explained circuit - very well done. I'm going to buy you a coffee. I have two questions about the circuit. 1. How could it be configured to be controlled by a 0v to 5v input signal? 2. How could it be configured to control a much more powerful DC motor - say 36V 600W? Thanks in advance.
Exceptional quality content channel. Easy to follow for the beginners like me. Thanks for the PCB download on this PWM module. I have a current project in need of this exact design. Thank you for the download.
I don't have a lot of components, BUT somehow I have exactly the ones I need! This is a circuit that I have did tried to build months ago, it didn't work my timer overheated, but I will try again with a diodes. Thank you!!!
It worked! I did blow one of my timers because the flyback diode came loose 🤣 Tip: if the 555 timer starts to heat up ( use your finger), something is wrong.
Thank you for this video! Fantastic explanation. I'm trying to do something similar but using a joystick to control a proportional solenoid for a hydraulic setup.
Ok, this was the first of your videos that just completely lost me at the middle point. I was just smiling and nodding, understanding very little when explaining the various wirings and logic inside the IC 😆 Apart from that, even I was able to understand the general idea of the workings of the chip.
I can understand the functionality of the components, but in a circuit that is supposed to be basic, the interaction of the components is very difficult for me to understand. I think I need more basis to start feeling comfortable with this kind of circuit, but man, what an incredible job this guy makes, I wonder how much time does he spend to upload a video like that, superb!
My only quibble is that PWM can be hard on smaller brushed DC hobby motors which also have high current draw (like those on RC helicopters and drones). Brushless handle it fine, but on brushed it will burn out the motor sooner. An adjustable buck converter would be a better option for those kinds of DC motors, I think, so long as the converter can flow sufficient current at the desired voltage (for instance, the motors I use in Nerf flywheel blasters generally have a max power current draw of around 14A and stall current of 28A at a nominal voltage of 7.4V for a motor speed of around 36krpm. Two of these are used in parallel with opposing polarity to propel foam darts darts out of a nerf blaster).
This is by far the most detailed explanation of how to design a controller. Thank you very much 🙏🏽 May I know whether this will work for a 36V 250W BLDC motor or whether I need make some modifications for it to work? Thank you once again 🙏🏽
13:16 Why is the resistor R1 connected to the discharge side too? Wouldn't the discharge pin of the 555 pull current through it from the 12V power rail?
Dear sir , lot of tnx to u i would request to u plz conver as much circuit as u can.. plz... & tnx a lot for such detail knowledge u r helping me to reach my goal . Of becoming hardware engineer.
WELL EXPLAINED LIKE EXPLAINING TO A 6YO! I got a question 13:05 Where you calculate the charge time of the capacitor, where does the number 0.693 come from? Thanks in advance
Poul - the bedst video I have see. Thank you. You are a genius. I am learning from you. For me it is so sad to see all that electrical waste that is thrown out. I collect and try to repaire. If I get the product to work, I give it away for free - that is my life. I am working with electical drill, robot cleaner, escooters, mobility scooters. My big lack of knowledge is to be able to repaire the controlers. Will it be posible for you to make a video - very simple, on how to trobleshut an controler. I will sugest that you make it with a controler from a mobility scooter. I have 2 now that I like to fix and give away.

This has got to be the best description of the internal workings of the 555 ic I have ever seen. Many thanks.
My favorite channel, and this is my favorite series!! You've really helped renew my interest in learning on my freetime. Thanks so much bro :)
Excellent to hear
Thanks for doing these series !! Being very new to electronics , I don't fully understand it, but thanks to your channel I am slowly piecing it together.
Aside from the motor controller circuit itself, this is one of the best 555 explanations I have seen, could be considered a video just for that!

Everytime I watch your videos, I always learn something and understand something in a way no one else has explained or made sense. Love the channel!
I really want to just archive all your videos. I don't want to see these disappear one day, as I want to keep this knowledge out there for everyone to have access to.
This is rated five wow's. Perfect explanation of the 555 TIMER AND CIRCUIT. Awesome video. Great teacher.
Brilliant, better than any book, presents in visual and audio form which helps me learn a lot. Thank you.
My senior project, I did it with a PLL control circuit 30 some yrs ago. I also did a digital version with 8051 microcontroller as comparison. Enough to earned me a degree. Bring back good memories seeing this.
Are you still doing engineering work?
Holly! This is the best electric video I've ever watched
I never understood 555 timer until I watched this video. Best explanation.
Thank you for this. Great explanation of how a 555 timer works in a pmw motor control circuit.
Great work. I have made this circuit almost 5 months ago. It really work perfectly. But i saw your channel first time today. You provided all information about it.
I have watched only 5 min of your video and I am subscribing such a good way of describing and in detail. Thanx and appreciate it.
Absolutely amazing how break down the explanations of components and how it will work within the circuit.
Thanks for the time spent on these videos. 🙏

Im gonna make this in minecraft redstone and show my electronics teacher.
How do u do the potentiometer
exactly what i was thinking
Can be done with 3 comparators... curious if it could be done with only 2.
May be your teacher is also learning from here.
Create mod would be perfect for demonstration of this circuit
Excellent explaining this video should have billion views...thx
its clear desription even for me who never learn electronics part and make me want to learn after watching your videos, thanks for education
I love how you show the circuit design, great job!
Never before seen better explanation of 555 ic, how it works. Very nice from you mate even nothing new for me but I know it will help many.
One of best, most educative videos I have seen. Thanks a lot.
Glad it was helpful!
Great explanation of a 555 timer chip function. Those little giants are use in so many circuits. Got to be the best little chip ever designed... Thumbs Up!
The PCB design & 3D modelling was the best part! 👏💯
wow u so amazing bro i really want to watch and learn you video, i will not miss your lecture. big thanks from Ethiopia
The best explanation of N555 🙏
13:12 It's 0.35 ms again, approximating. It doesn't change much, though! Great job!
lemme tell you good this video is and generally this channel: I got mad when I saw, that I was not subscribing... I clicked it like a Blitz!
YOU'RE SUCH A VERY EXCELENT TEACHER. KEEP IT UP.
Thank you! 😃
At 5:02 you said you add a fly back diode and on the image it says flywheel diode.
I love your content you teach all the little details, keep up the great work!
It is called a flyback diode or freewheel diode, I've accidentally mixed the two words
Rarely have I seen such a well explained circuit - very well done. I'm going to buy you a coffee. I have two questions about the circuit.
1. How could it be configured to be controlled by a 0v to 5v input signal?

14:45 It is recommended to place the screw terminals closer to the MOSFET and have the traces exposed so more current can flow.
Why is that? Genuine doubt here.
@@laypyu Avoid resistance if you can.
@@TheUnknownCatWarrior Ah yes. Got it. 👍🏼👍🏼 :)
