Bidirectional DC Motor Speed Controller Electronic Kit from DIY Electronics
This kit allows controlling the speed of a DC motor in both the forward and reverse direction. The range of control is from fully OFF to fully ON in both directions. The direction and speed is controlled using a single potentiometer. Turningthe pot in one direction causes the motor to start spinning. Turning the pot in the other direction causes the motor to spin in the opposite direction. The center position on thepot is OFF. This design avoids the need for a direction reversing switch and avoids mechanical and electrical stress by forcing a smooth transition from one direction to the other.
