i am new to arduino and stepper motors. I bought from eBay arduino compatible and unipolar motor. My plan is to control it via PC and install motor on focuser of telescope, so i can focus my telescope with stepper motor. I also install Arduino 1.0 for windows (programing), but i have no idea what to do. Plan is to control stepper with speed 1,2 and 3 and backward-forward. Can someone help me on this please ?
