  • Does anything happen? Have you tried any of the stepper example programs, and do they work? How is your stepper connected? A diagram would be helpful. Is the power supply sufficient for this motor? Can you confirm the supply is working? There is a lot more you could provide in your question - or check for yourself and and provide that information - to help us help you. Commented Jul 15, 2019 at 11:38
  • @JRobert so it's supposed to keep rotating at 180 degrees with breaks right, but it just rotates once and stops. I was wondering if the power supply would be a problem because right now it's connected to the Arduino. I'll get a power source tomorrow and try again. IN1,2,3,4 were connected to pins 9,11,10,6.

  • @JRobert, I checked out another video and changed the pin configuration. Other details are updated in the question. If you need any other information then just let me know :) Commented Jul 15, 2019 at 12:17
  • Most motors need more current than an Arduino pin can supply, so if the stepper driver doesn't power your motors through a separate supply, there is a good chance that is your problem. Arduino pin drivers are supposed to be limited to 20ma nominal, and 40ma absolute max. Trying to draw more than that will likely fail (the device will be under-powered), may damage the pin drivers (by over-heating), and may pull down the Arduino's own supply voltage enough to it to reset (typically cycling itself through startup/attempt to run/reset, ... etc. until you shut it off or something fails).

  • Hey @JRobert!!! I finally got it working!! So what I did was connected the motor to a 5V 0.3A supply. And then I changed the number of steps per revolution to 2038 and used the code on Michael Schoeffler's website (mschoeffler.de/2017/09/23/…). And it finally works!! Thanks for all the help :) Commented Jul 16, 2019 at 5:11
