Datasheet and Circuit Diagram, Posted by: admindata at August 3rd, 2010
We can interface two DC motors which can be controlled in either clockwise and counter clockwise rotation. A schematic example for interfacing a DC motor using L293D is provided herein:
As seen in the circuit above, A , B, Enable pins are needed for interfacing a DC motor. In order to make the motor work, you may connect Enable to VCC and only 2 pins needed from controller, it will make the operation to be enabled completely.
