L293D Motor Driver IC and interfacing with microcontroller

Hello Engineers, Whenever making motor-based projects using any microcontroller IC we need more power in order to operate the motor. This power, can not be provided by any of the microcontroller ICs as motor requires a lot of power than the microcontroller consumes. For this, we need to use a motor driver with a microcontroller(L293D […]
