“The project presented here is a low-cost easy to use DC brushed motor direction controller with fast-brake, the project was built using two 12V Relays, 2 x BJT transistors, and 2 x tactile switches. The two LEDs are provided to display the motor direction, 2 tactile switch controls the direction of the motor.
Connect 12V DC power supply to connector CN1, connect 12V DC brushed Motor to CN2. The motor will run in any direction by pressing any of the switches, other switch will rotate the motor in another direction. When the user leaves the switch fast brake apply as both terminals of the motor are short when both relays are in an OFF state.”
