I set up my 5VDC stepper motor with a few female-to-male wires, a power supply, a driver module, and a UNO R3 with the code from File -> Examples -> Stepper -> stepper_oneRevolution.
I wanted to make it move faster and, for some reason, the examples I got somewhere else made the role-per-minute 15, while the example from the Examples made it 60. In the example I got somewhere else, I turned it to 20 without reading the comments, and the stepper's not moving, so I turned to a 2 and it moves, 15 again and it's not moving. I thought it was stuck so I turned the thing that turns by my hand and now it's not turning at all.
I don't want to get a new one yet since it's still pretty new, so can I somehow fix it?
