Skip to around 10:00 for the switch demo
In this quick n dirty video on stepper motors I explain the difference between unipolar and bipolar stepper motors and even control one using only pushbuttons. This helps to visualize the sequencing needed to rotate the shaft in either direction. I also demonstrate full-step vs half-step control.

The best explanation of how stepper motors works and how to control the steps I have seen! Thank you for taking the time to explain the fundamentals of operation, explaining the circuit, and using a cardboard labeled with degrees to visualize.
Keep up the great work Kev. I am sure we all appreciate your time and effort.
I love how you break things down to simple terms to understand the whole picture. Thanks!
Have watched quite some stepper motor videos but this was by far the best one. A very cool way to explain it - this is how it should be explained in school or entry level electric studies!
Congratulations on probably the best stepper motor tutorial on RUclips - well done!
Thanks for taking the time to explain this. What a great learning tool. Seeing it work in its most basic form really drives the point home. Very cool
Thank you Kevin! Loving these push button break downs. They really show you what you have to do in the code.
Super great explanation! Thanks for making and sharing this video.
Practical and straight-forward, as always. Love it.
Keep calm and control the shaft in a very precise way
You explained the concept easily and simply . This helped me a lot . You really deserve a medal for this
FINALLY!!!
A good, sane explanation about a stepper motor driver!
The best and the only, actually!
I was fuzzy about the stepper motor driver functionality. I didn't understand it's purpose and what used for and finally, I understand it!.
Thanx a lot!
Thanks for that. Concise, clear and understandable. I now know heaps more than I did before, on this subject.
This is exactly what I needed! I haven't built this yet, but it looks like an excellent way to get an intuitive feel for how to control a stepper motor.
Thanks!
Thank you VERY MUCH for making this video!! Really-impressively simplifies what's actually going on in the H-Bridges and motor driver!
That was a cool demonstration!
Thank you for taking the time to make it.
Thank you so much for this! I was able to figure out what i was doing wrong with the stepper motor. I didn't stop to think that i could do each coil one at a time!
Best video on the subject, all that i wanted to see! subscribed!
nice intro for stepper motors. Took a degree in electronics back in the 80s and never touched the subject again even as a hobby. So much has changed and an awful lot hasn't changed at all. Still, your videos are clearing away the cobwebs so thanks again.
Thank you so much! This helped me a lot to understand how stepper motors work, as I never learned very well :). Keep making this kind of videos, I'm sure they help a lot of people like me.
Useful and easy to follow video, great job on explaining it very clearly.
Awesome vid Kevin; I was watching a lot of your tutorials to make my own. Keep up the good work!
Very Helpful!! You are a good teacher and I like the way how you have bolstered your explanation with a white board and a live example!
I love these videos. You make it so simple. Hope you keep making them.
Excellent and easy to understand explanation. Thanks for sharing.
I think you just solve an issue with a Stepper Motor project I was having.
Fantastic explanation! Thanks for taking the time to share that!
Good explanation Kevin. Easy to follow. I'm a CNC programmer from way back and the electronics has always been a bit of mystery.
Thanks for this super simple explanation. Exactly what I was looking for.
This answered every question I had about stepper motors, nice and easy to understand as well.
In the US Navy's Basic Electricity & Electronics school (called "B-double-E" school) we approached stepper motors in a sequence of increasingly complex control mechanisms:
1. Take two batteries, one for each coil, and flip them together/separately to make the rotor turn.
2. Do it with one battery. Getting the leads connected and moved was hilarious.
3. Use pushbuttons, as done in this video. Notice the smoke from the wires melting their insulation when fingers get confused.
4. Replace the pushbuttons with a pair of DPDT center-off toggle switches. Muuuuuuuuuch easier.
5. Replace the toggle switches with H-bridges.
Success! Our stepper motor collection included some the size of a peanut, up to the size of a 5 gallon bucket, and we got to control nearly all of them. We felt so good.
Then came Synchros, Servos and Control Transformers...
In a practical manner you demonstrated so clearly the function of a stepper - great
Excellent! Thank you so much for making this video!
Watched a lot of stepper theory videos. This short video cleared up a lot of my confusion. Will be watching more of
your videos..
i didnt need any of stepped motor informations at all but i satisfied with the explanation and diagrams and actual practical motor demonstration. I really loved this video
U r awesome Kevin
When you were sequenceing the buttons I thought "wow, is he actually going to be able to do that" lol. Good job. Great video

Kevin, you are awesome! This was so helpful, as are all of your videos!
Thank you! Again, you've made it really easy to understand :)
First time I easy understand H bridges applied to Stepper. Thanks you so much
that was probably one of the best explanations I've seen on stepper motor fundamentals .
Good job, dude. Crystal clear explanation. Thx a lot!
Great! Please consider continuing the tutorial - MOSFET selection and software control. I always look forward to your tutorials - very well done.
Brilliant, so interesting to learn - thanks for showing
Awesome explanation.Keep up the good work bro!
The board with the printed protractor is an excellent idea. Great learning tool.
Your demonstration is excellent. 👍👍
great video! definitely helpful in understanding how to control stepper motors
nice brief on stepper motor ... its understandable video for those who want to know about the working of stepper motors
hi, thanks for the video, it's very cool. question - i read from some other articles that when running and reversing power to the coil really quickly, it would create back-kick effects, and so capacitors and droids are needed? what's your thoughts?
I am sure all appreciate your time and effort.Thanks.
Your videos are the BEST!!!
hey Kevin, that was a great video on stepper motors, yeah I would be very interested to see a video on how you would connect the mosfets and a follow up video. thanks!
This is very cool and informative! Subbed
Clear, concise, and short. Thanks.
Great Tutorial!!! I wonder if you know of any "higher level of abstraction" ways to control a stepper motor. I was considering getting into Arduino in order to control my blinds, or some other home automation, and I wonder if I could find some software to say "Go Left X number of steps" or "go right x number of steps." etc... any ideas?
Great video - I have a much better understanding of stepper motors and how they are controlled. Thanks!
Thank for the explanation. I am trying to get a foam cutter board working that uses a mm2001 board with unipolar steppers. You mentioned using mosfets. As this board uses large resistors and they get hot, I was thinking about trying to figure out how to use mosfets to change things so there would not be so much heat. I am only a hobbyist with electronics, but it would be a great help if you did do a video showing how to move unipolar steppers with mosfets that were driven with a uln2003.
Thanks for the video.
Di Caprio Double explains electronics! Nice video mate!
Very nice idea and demo!!
Interesting and informative video... I'm just getting into the Raspberry Pi, so has been helpful... Many thanks :-)
Great explaination...keep up the good work
Question, what will happen if you cut one of the wires to the stepper motor? When using hybrid synchronous stepper.
hey Kevin, what do I use to capture specific range in frequency to activate a specific stepper motor that is programmed to do a certain rotation in commands? Does the information have to be MIDI already then fed into this ...(thing i need to talk to specific motors)... or can I just get some device that doe this automatically?
cheers
fantastic explanation for the beginners to understand
Really clearly explained! Thanks :D
Very interesting video!
Great tutorial - well presented.
Awesome video as always!!! :)
Thanks, man - very instructive!
I made a driver from an h-bridge plan I found on the Internet. It seems to work fine, but I can't get any speed at all. I got a small boost by carefully adjusting the time between pulses, but it felt random - if I switch to another motor I would have to tune/guess again.
Is there a way to achieve high speeds or tell what a reasonable speed is?
Very well explained. Thank you!
Very clear tutorial. Thanks!
what is the Vcc value you are using?
Very helpful.
Another great video.
Very interesting. Thanks for posting.
Give this man a medal
very nice simple demo.
Great video that explains them well.

hey kevin, i would really like to ask u smth and hope u'll answer. its about 8x8x8 rgb led cube. well im building it now and i wanted to use ur code to control it, so: here's the thing i wanna ask: we know that the 74hc595's are daisy chained together so where (numericly) is the shift register which controls the layers is located i mean the anode control one. is it the last? hope u answer. love ur videos
Thanks for sharing your knowledge.
Can I connect the center wire of unipolar to negative and others to vice versa this is working fine for me? Is there any catch?
Great video, thanks!
Cool broadcast, thanks...
Nice video. I had that degree scale before but I lost it. can you give us link for that degree scale ? I think it was a vector graphic.
Good detailed explanation. Suggestion: Get some 'Sharpies' and color code the switches and create a color coded sequencing table on paper. Thanks for sharing.
very helpful video. thank you bro
great explanation. Thanks so much
If the spec sheet does not indicate the voltage, but it does the current, how do you determine what supply voltage to use?
Good job for this vid. Thx for sharing.
Very good explanation
Great video Good stuff, Thanks!
Did U-do a review on RUclips of the X-carve?
Good Job brother!
wow, thanks a lot kevin, i've learn a lot from your video, i wish you could also release a vivid instruction on how to revive an AVR MCU due to fault fusing of a newbie like me :D, TIA
Good pedagogy. Take this into class.
Diagram at 8:00 When a switch is closed the circuit is still broken.
OK need 2 switches, I didn't get to that bit yet.
Very informative video. Thanks.
beautiful information.
great explanation thank you
Nice demo thanks. :)
you made my day thanks
Thank you very much for this video. But could you explain why it makes 1.8 step and 90? because of multiple poles on stator?
+human being I meant why 1.8 and NOT 90
excellent vid, super excellent!
