Lines: 17 Hi, I took apart an old hand-held scanning laser bar code reader, and the motor which controlled the multi-fasceted mirror (which moved the beam across) says "step 15(degrees)" on it, and has 4 wires - red, black, yellow, gray. I assume some kind of sequential voltages on the wires makes it turn. Can anyone tell me more on how to operate the motor? Thanks, Steven -- Steven V. Christensen U.C.
