These pins actually control the switches of the H-Bridge circuit inside L293D IC… Input logic 00 or 11 will stop the corresponding motor. This current will then fall down 150 – 200 mA as the motor gains speed to around. If you want to run motor reverse then give Pin 2 LOW/0V and Pin 3 HIGH/5V. Input logic 00 or 11 will stop the corresponding motor. Using the direction control pins, we can control whether the motor spins forward or backward. By Mr innovative My website Follow. Enable pins 1 and 9 (corresponding to the two motors) must be high for motors to start operating. This means that there are a lot of connections to make on the breadboard. When Pin#1 is high and Pin#0 is low, motor rotates in anti-clock wise direction. To Control first motor (left), you can give input from microncontroller like arduino to make motor run forward or reverse. DC Motor is an actuator that converts the DC supply to rotation or movement.
