Motor speed controller tutorial - PWM how to build

Electric motor speed controller. In this video we learn how to design a simple PWM speed controller for a DC motor learning how current flows in the circuit and what each component does. You can even build the circuit yourself!

Please don't stop this circuit design series.
It is really great.

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!

This has got to be the best description of the internal workings of the 555 ic I have ever seen. Many thanks.

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. :)

This is what YouTube is all about. Thank you so much for making these!

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.

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.

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.

As mechanical engineer, how I can't fall in love with electronics, if it's not explain this way. wonderful tutorial from a great mentor. thank you

[AlmondBuddha]

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 :)

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!

[strage]

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.

This is rated five wow's. Perfect explanation of the 555 TIMER AND CIRCUIT. Awesome video. Great teacher.

[Imstilllearninglife]

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!

[brs.l.bs.p]

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.

[grahamhall]

Brilliant, better than any book, presents in visual and audio form which helps me learn a lot. Thank you.

[larryreno]

Thank you for this. Great explanation of how a 555 timer works in a pmw motor control circuit.

[jumbo]

I never understood 555 timer until I watched this video. Best explanation.

[nhattienle]

Holly! This is the best electric video I've ever watched
