Arduino Tutorial 37: Understanding How to Control DC Motors in Projects

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:

This lesson shows you how to control a DC motor using arduino and a L293D Motor Controller. It is important to make sure to use motors compatible with the current capabilities of your control chip and power supply.

You can get the kit I am using for this series at the following link:

Nearly 40 videos in and I haven't *really* said thank you yet, so here's my thank you! You deserve a lot more than this, sir!

For anyone that was ever wondering, this is actually why fans, like box fans, oscillating fans, etc, have high as the first speed on the dial. It's to kickstart the motor 🙂

Why does internet teach me better than the school I'm forced to go so I can find myself a future?
This sir has taught me in under 1h everything I've been trying to learn in a whole week at school

Thanks a lot!

Rose and Ronald. Great tutorials! Everything pedagogically and clearly explained, packaged and delivered in a professional manner. Some things have obviously happened on the electronics front since I studied to become a merchant marine engineer in the 80's. Now I have a lot of catching up to do as it seems ;) Thanks a lot for your tutorials, time and effort!!

Rose and Ronald!
Thank you so much for the “positive energy” you are giving us Mr.Macwhorter❤

[pranavsudhir]

Sir, these lessons are top notch nothing on the internet beats your Arduino content. Excited about your upcoming premieres.

[thomashicks]

I have run through all 37 lessons and they all work fine. I do listen to the whole lesson. Rose & Ronald

I know I'm 3 years late, but this series is as awesome as roses!

Had to slow down over the last couple of days. My L293D chip was bad. Learned a lot about troubleshooting and finally figured out my chip was likely bad. Ordered some more and now I am in business. Everything works. Great lesson! Rose and Ronald.

ever since I got an Arduino I also watched different tutorials on Arduino but after I come across your channel I found all the needed fundamentals on Arduino and I just love your content been 3years since released and still doing wonders

I KEEP WATCHING; GREAT TEACHING; WE NEED MORE TEACHERS LIKE YOU:

[deanrussell]

I’ve watched every single episode of the new and the old arduino tutorial series, from start to finish, keep up the great videos Paul, Rose and Ronald 👌🏻

[devyanshusinghal]

"Rose&Ronald" gave us this great series of arduino. Best series I have watched so far.

[lewisencompos]

Thanks Paul. I've learned a great deal from your videos. Better series than 30 days lost in Space and much more pleasant to watch!

[ErlankBru]

I always watch until the end. Thanks to Rose and Ronald for keeping the yard nice and tidy!

[luisatierney]

Rose and Ronald :) Thank you so much for making these videos, they're super helpful and very much appreciated! I'm a university student studying Computer Science and one of our classes is all about embedded systems. We cover a lot of material in class and usually if I'm struggling on something in particular, I come along to your channel because you explain things so well. It's great that you're easy to understand/follow and I also like how you repeat key concepts, making it easier for us to remember.

Your videos have been especially important during the 2020 Coronavirus quarantine period, since us students haven't been able to attend classes - These videos have been a real saving grace for us, and I cannot thank you enough for taking the time to record and upload these videos. God bless you.

Ronald and Rose. Thank you for a brilliant series of tutorials. I suspect I would not be the only one to say how much you are helping me to get through this lockdown ! Thanks again.

Merry Christmas Paul, Rose and Ronald!


I’ve been watching your Arduino tutorial series from lesson 1 and have been able to follow along up until this lesson, always doing the assignments before watching the video and have been able to successfully do the math and all without much problem. That is because of your most excellent teaching of course. I’ve learned so much since I started watching your Arduino tutorials about a month ago. I literally didn’t even know something like the Arduino existed till the beginning of this year when I started watching videos from Mark Rober, the Hacksmith and Colin Furze and discovered the world of engineering, electronics, machines like 3D Printers and CNCs and CAD. I was blown away and fascinated at the machines and at what these guys were able to design and build and was always hearing them say they used an Arduino for certain parts of the build.


It was until 2 months ago that I finally decided that I wanted to learn how to use the Arduino so I bought it but was overwhelmed and did not know where to begin since i basically knew zero about electronics or programing and the tutorials I watched kind of assumed the person already knew a bit of what they were talking about and so I was beginning to feel a bit discouraged until I found your Arduino tutorial series and with your most excellent way of teaching I began to understand how the Arduino worked.


Your videos and your teaching is amazing because i have not only learned how to build circuits, how to write code and how to troubleshoot but i have also learned Math and Physics and how some components work at a fundamental level.


I am very grateful to you for making these amazing lessons and making them for free and I am very excited to continue learning. I am also planning on watching your Fusion 360 Tutorial Series because I also want to learn CAD and how to 3D Print.


Also for this lesson’s assignment, I decided to challenge myself and see how much I’ve really learned from previous lessons and did the assignment but I tried to incorporate every component we have learned to use so far. I hooked everything up, wrote the code from zero using everything I’ve learned so far and once I uploaded the code and saw everything worked perfectly and exactly as the code was written and based on the math, i was blown away. It was a very rewarding feeling. I was smiling the whole time!


I uploaded the video on my channel and put the code in the description if you would like to see it and maybe grade me on my progress so far XD.


Again, thank you so much for making these amazing lessons and I am pumped to see what we will be learning next.

Merry Christmas!

Rose And Ronald, Love your videos dont know what id do without you. Thanks!

[raffaelevirgilio]

Rose. Great Tutorial. I started going through this tutorial 3 days ago and I followed each lesson beginning to end (including homework). I am so glad you pulled this series together Paul. Well done!!!
