The system used a small brush motor with a speed reduction gear to both latch and unlatch the door. Hobby Circuit designed by David Johnson P.E.-February, 2007ĬW & CCW Alternating Motor DriverA while back a company needed a motor controller for a custom door latching system. The circuit can control power and direction of a DC motor.
