DC Motor with L298N Motor Driver
Article directory
In this article, we will explain how to drive a DC motor with the L298N motor driver using the ESP32.
1. Introduction of L298N
The L298N motor driver module is very easy to use with a microcontroller and is relatively inexpensive. It is widely used to control robots as we can connect up to four motors at a time, but if we also want to control speed and direction then it allows two motors to be connected. Therefore, it is very suitable for two-wheeled robots. This module is mainly used in robotics and controlling DC and stepper motors.
The L298N Motor Driver Module consists of the L298N Motor Driver IC, 78M05 5V Regulator, 5V Jumper Enable, Power LED, Heat Sink, Resistors and Capacitors all combined in one IC. The diagram below shows all the components contained inside the module.
The L298N motor driver IC has a built-in large heat sink and is powerful. It is a dual-channel H-bridge motor driver that can be conveniently used to drive two motors.
The module also has a 78M05 5V regulator which can be enabled via a jumper. Leaving the jumper intact means the 5V regulator is enabled. If the motor power
