This is by far the finest most extensive video out there on steppers, and differences, pro’s-cons. The video is at a great pace and easily followed. This video is WELL worth watching and provides high value to the audience. Thank you for the time you took for all the details explaining all the parameters as well, including the math calculations. This video IS education!

Best explanation I’ve seen. Many thanks.

Excellent series! Thanks for an amazing job.

Highly recomendable video on stepper motors, it takes you to the core in simple words. - I've not seen anything better, I seen a lot.

[marwanshwaiki]

Excellent demonstration indeed. Thanks

[Hellbrate]

You earned subscription. Nice tone of your voice, calm and precise. I really enjoyed watching your video and following your code. Keep up good work!

One of the best stepper motors tutorials! It gives a lot of inspiration to me creating a gauge with Arduino.😀 The videos will come later this year.

[hernanjavines]

Thanks for the video, it helped me debug Arduino's sample code!

One of the best Video on Youtube, very clear instruction and with ampules of information, Thankyou .

[quoctrungtran]

This helps me alot. Thank you so much for your awesome video.

To jest najlepsze wyjaśnienie jak działa motor. Myślę, że wprowadzone biblioteki i różna wielkość ilości kroków na jeden obrót i kolejność podłączenia uzwojeń spowodowała że straciłem wiele czasu na zrozumienie jak działa motor. Gratuluję efektu i pozdrawiam z Polski.

thanks for the finally i understand the reduction gear ratio, excellent explanation by the way, the best way to understand how it works something is not using arduino libraries :D

[digihz_data]

The best professional explanation I ever seen, and he is so calm to in his speaking.
Great!

[nicolaumonteiro]

THAT WAS OUTSTANDING... IT MIGHT HAVE BEEN THE BEST YOUTUBE TUTORIAL I HAVE EVER SEEN. WISH YOU COULD CONTINUE THIS SERIES ABOUT ELETRONICS/ARDUINO.

The best video abut stepper motor and Arduino. Congratulation. Best Regards.

Came here for info on speed variation, but will for sure go to Chapter 1 and give this series a go.
Well explained.

This is by far the best video ive seen on the 28-BYJ-48

The motor is great for simple tasks but really starts to struggle at 5V with the ULN2003 with anything demanding torque or precision.
For that reason I love running a modified 28-BYJ-48 with an A4988 at 12V 120mA.
You can get much higher RPM (I tested to about 25-30, but ofc you will lose torque) Or get a lot more torque at the same 5-12 RPM.
Sure the ULN2003 can be run a 5V, from the same source as the microcontroller but the 28BYJ48 and A4988 Combo can easily be run on a cheap 5V to 9/12V boost converter, which offer a small footprint and enough current capability to run the Motor/Driver reliably and without overheating.

Hi there! Excellent video! I am working on a project using 28byj steppers and the “precision problem” is the cheap gearbox with a huge backlash - so, when you change direction, a few steps will be “wasted” until all the gears get in traction contact again. The AccelStepper library has a setBacklash method that could potentially fix this... didn’t test it yet myself. It looks like:
/// Sets the number of steps needed to correct backlash in drive train
void setBacklash(unsigned long steps);

Hope it helps!

Great video. Please tell more about terms like maximum speed and acceleration. Thank you.

Thanks very much!
Please can you put the link to the guide you found in the description?
