Also, the output current limit of Arduino is relatively very low. But a decent DC motor needs at least 5V or 12V. For instance, the Arduino or PIC microcontroller can output a maximum voltage of 5V or 3.3V. Why do we need a motor driver module?Īll microcontrollers operate on low-level voltage/current signals, unlike motors. The IC alone can control the DC motor, but using the module makes interfacing with Arduino easy. The motor driver module consists of a motor driver IC, which is the heart of the module. To put it in simple words, you can control the direction of DC motors by giving appropriate logic to the motor driver module.
This input logic controls the direction of DC motors connected to the driver. A motor driver module takes the low voltage input from a controller like Arduino. It is commonly used in autonomous robots and RC cars (L298N and L293D are the most regularly utilized motor driver chips). A motor driver module is a simple circuit used for controlling a DC motor.
