DC Motor Forward/Reverse Control with Relay 🔄

This video demonstrates the circuit built to do either forward or forward and reverse control of DC motor which in this case, BO motor. BO motor stands for 'battery operated' motor which is extensively used to drive the 2WD/4WD robot cars.

The Arduino code to make the motor run forward and backward continuously with 2 seconds of duty cycle as shown in this video: https://goo.gl/iN7sfr.
