The H Bridge Arduino Motor driver controls the voltage to the DC motor in either direction. This circuit is used for controlling the RC car or controlling the movement of the conveyor belt.
The circuit controls the rotation of the DC motor in one direction at a time, like clockwise and anti-clockwise. The Arduino helps the motor to control the bi-directional movement. Let’s check out this simple circuit and the working of the H bridge motor driver controller using Arduino.
What is h bridge mode of operation?
The h bridge circuit is commonly used to control the motors direction of rotation. This circuit allows the direction of current in any one direction at a time. It will be like the back and forth movement of the motor. To configure this circuit either transistor or mosfets are using. Two pairs of transistors or mosfets control the DC motor direction. The H-bridge can operate in four different modes, depending on the states of the switches like,
- Forward mode
- Reverse mode
- Brake mode

H Bridge Arduino Code
This circuit is widely used in robotics, electric vehicles, and industrial automation for precise motor direction and speed control, Arduino-based circuits typically control the switches in the H-bridge through an Arduino IC (ATmega328P) or other microcontroller to achieve the desired functionality.
