I need to use two stepper motors to move microscope positioning knobs in the X/Y direction. The stepper motors I have are unipolar and are 6V rated (I think).
I know it's possible to drive a unipolar stepper motor via a ULN2003 using an Arduino Uno. I know I can wire it using the 2-wire or 4-wire method.
But my questions are:
Is it possible to drive 2 of them? What are the modifications I will need to make to the circuit? Will this harm my Arduino? Do I need a stepper motor shield?
