I need help...
I am working on a project that includes unipolar stepper motor with 5 wires, 48 steps,7.5 degree/step.I have L293D motor driver and a spartan 3E starter kit to control the stepper motor.
the main problem that i want to know the exact current position to rotate it toward the north pole. I know that i need a compass to do that.
But i have no idea how to do that..
what i need:
How could i know the current position of the shaft?
How could i rotate it towards the north?
thanx...
