Hello, I'm a total beginner at arduino and controlling steppermotors showed to be more than I could handle, so I need your help. I'm trying to complete the "stepper motor knob" project in the arduino learning examples library and I'm all out of ideas of why it's not working. I'm using the 57BYGH4…

Doomrazor:
I'm using the 57BYGH420 unipolar stepper motor together with the UNL2004AN Darlington array.

Motor rated at 3V 2A, ULN2004 array rated at 500mA absolute maximum. See an issue?
