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.

Probabally have to build one then.
If running the stepper at fairly low RPM, you may not need supply over-voltage and could use the stepper rated plate voltage.
Max.
