In this tutorial, we’re going to build a few example projects to demonstrate how to use the L293D to control DC motors on the Arduino. To turn the motor OFF, send a LOW signal to the input 2 pin. To make the motor spin in the opposite direction, send a LOW signal to the input 1 pin, and a HIGH signal to the input 2 pin. This will cause the motor to spin in one direction. To turn the H-bridge 1 motor ON, send a HIGH signal to the input 1 pin, and LOW signal to the input 2 pin. ![]()
