How do I drive a 4 wire stepper motor?
Im thinking of making a small CNC machine to make PCBs. Just the other day, I opened up an old scanner and found this stepper motor with 4 wires. The wires are orange, yellow, light brown, and red.
The info on the motors label is:
1.8 DEG/STEP 4.1 Ohms
How can I drive this? Can I use an arduino, serial or parallel port?
