Bi-direction Control Circuit For DC Motor  This circuit can control direction of a DC motor.  In many applications we need to operate the motor in both directions Clockwise and Anticlockwise (forward and back). One way of achieving this is to connect the motor into a Transistor H-bridge circuit arrangement.

This circuit can control direction of a DC motor. This can operate the motor in both directions (Bi-direction) Clockwise and Anticlockwise (forward and back).
