Help! I am working on a solar tracker project and I need to know what motor controller I need to drive 2 stepper motors with Arduino. I don't know if the stepper motors will be unipolar or bipolar. More than likely they will be bipolar.
Don't know the current they will need either. I will have to rotate a roughly 11 lb panel in both azimuth and zenith directions.
