How PWM works | Controlling a DC motor with a homemade circuit

They work during chinase new year!

This is a very cool electronic project to control DC loads using a ver cheap and reliable design.

This video also explains in deph all about PWM so you can understand it easily.

I spent 30 years designing PCB's, beginning with hand taped boards on mylar sheets all the way up to sophisticate auto-routers. Still, It's amazing how far things have come. $2 boards, crazy!

It’s so enjoyable to finally see an really professional made tutorial. Not only that but also the video is top class. All the kudos to you Sir. Highly recommended.

This video is very beautifully completed. Not only great explanation about PWM, but also how to create fully working circuit as well as smooth ads integration. Bonus that nice flow motion time-lapse 👏

First time seeing that $30 oscilloscope(Amazon diy oscilloscope) used. Now i'm ordering it. Thanks for using it, and making this video.

Seeing the representation on the oscilloscope really helped me understand how PWM works. Thanks for the great demonstrations

Thanks for making this video. I was looking for PWM tutorials mainly for sound processing but this was incredibly informative. Also I didn't realise that PCB's were so cheap to buy, I'll be using those a lot more in my circwits. Many thanks buddy

You just make the thing enjoy itself. Amazing tutorial! keep this productivity.

Beautifully presented and very clearly explained. Thank you for taking the time and effort to create this video.

Seriously amazing video with a lot of great info. Thank you so much for making this video. I can't wait make this circuit for myself.

I learned about pwm from this video and I hardly know anything about electronics. It's thanks to your very good demonstrations. Keep up the work please.

Sir, you perfectly explained the pwm, thanks a lot.

I assembled my first pwm motor controller using assemblies from Amazon. It worked perfectly and allowed my old VW to have AC w/o fixing the defective computer. Thx!

Very great teacher, you are, Master of the 555. No joke, I learned why we use Pulse Width Modulation with you here and what uses it has. It cleverly limits sordid power dissipation too! Perfect crash course on the 555. Thanks Master. Thanks a lot.

i have a PWN controller in my house that i use to test DC motors, now i finally know how it works.

I am not an electronic/electrician guy, but your way of explaining is very good. Thanks for your effort 👌

Good job informing, presenting, explaining and linking with sponsors. Thanks.

4:00 for led's we dont use pwm to decrease voltage, same goes for majority of usecases, pwm is mainly use for quick on/off while still having high voltage, just not nonstop, for led or dc motors you need to have high enough voltage to run them at all, so you use time, not voltage to control brightness or speed. Pwm is used for decreasing voltage only for variable voltage output and you need to have inductors and caps on the output, for example VRM for cpu/gpu in pc.

Excellent video! Very informative, excellent production quality and to the point. Thanks!

Really a good video, simple to understand and clean.
Thank you for this tutorial.

Thanks for teaching. Doing electronics is an ART.
