Ive searched and read the other entries on the forum but still Im clueless. I am trying to drive a Haydon 35402 stepper motor 5vdc, 2.5 w 15 degree (bipolar) It looks as though it has 2 coils. The top one has red and black wires. The lower one ha blue and green wire.I have been using the code from here :http://www.picaxe.orcon.net.nz/stepdemo.bas. I can only to get the motor to "twitch". Im not sure if code isn't right for this motor or I have the wires hook up in the wrong order. ( I can't find a datasheet on this motor ) . Any help is appreciated.
