Introduction
The motor driver modules are devices that are used in autonomous robotics and embedded circuits to operate motors. A motor driver is unquestionably something that causes the motor to move in accordance with the given commands or inputs; high and low. It takes the low voltage from the controller/processor and uses it to operate a real motor that requires a high input voltage. A motor driver, in basic terms, regulates the direction of the motor in response to orders or instructions received from the controller. The motor driver takes signals from the microprocessor and converts them before sending them to the motors.

Applications
Robotics
The motor driver can control DC motors using Microcontroller. You can drive a DC motor forward or backward using H-bridge integrated circuits (ICs). This is especially useful when you are working on robots like robotic cars, etc.
DC Motors
The Motor Driver Module is a medium-power motor driver that works well with DC and stepper motors. It makes use of the well-known L293 motor driver IC. It can turn on and off four DC motors or regulate the speed and direction of two DC motors.
