![]() ![]() This Pin will provide the output for Motor A.Ĭonnected to Power supply positive pin for running motors (4.5V to 36V)Įnable-B pin is used to control the speed of Motor B. It needs to be connected to the power supply ground(negative). If both the inputs are either HIGH or LOW the Motor A will stop. When one of them is HIGH and the other is LOW, Motor A will start rotating in a particular direction. These are used to control the rotating direction of Motor A. If we connect this pin to Ground the Motor A will be disabled. In that way, we can control the speed of Motor A. If we connect this pin to a PWM input of the microcontroller. If you connect this pin to +5 V, Then the motor will be enabled, then the Motor A rotates maximum speed. L293D Motor Driver IC Pin Diagram/Pinout/Pin Configuration Pin NumberĮnable-A pin is used to control the speed of Motor A. ![]()
