Motors

There are two motors for each mirror. Each mirror has an up/down motor and a left/right motor.

All motors are reversible. For example, the mirror is moved up and down by one motor. When the MMM receives an input to move the mirror up, it supplies battery positive voltage (B+) and ground to run the motor to move the mirror up. When it receives a mirror down input, the MMM supplies power to the same motor. but the voltage and ground are on the opposite motor cavities. The voltage polarity is reversed and the motor runs the opposite direction, moving the mirror down.
