whole laser assembly is on to metal shafts, with a 3rd shaft that sorta
looks like a screw, when i spin the screw shaft the whole laser assembly
moves either up or down the other two metal shafts. the screw shaft is
attached to a small circular motor, about the size of a penny, and half an
inch deep. It has 4 leads. Is this a stepper motor? How would i get more
information to make it usable. Ive never used a motor before, so any help
would be great. I would be using a atmel 89c2051 to interface with it.
