Arduino Uno H-Bridge Module Control

This project demonstrates how to control two DC motors using an Arduino Uno and an H-Bridge module.

The H-Bridge allows bi-directional control of the motors, enabling them to move forward and backward with varying speeds using PWM (Pulse Width Modulation).

Components Needed

• Arduino Uno
• H-Bridge Motor (L298N or similar)
• two DC Motor
• Power Supply (for motors)
• Jumper Wires

Hardware Wiring Explanation:

Connections to H-Bridge Module:

in1Pin (H-Bridge):

in2Pin (H-Bridge):

enAPin (H-Bridge):

in3Pin (H-Bridge):

in4Pin (H-Bridge):

enBPin (H-Bridge):

• Connect the Vcc and GND of the H-Bridge to an external power source suitable for your motors.

Software (Arduino IDE):

Open the Arduino IDE and create a new sketch.

Copy and paste the provided Arduino code into the sketch.

Power the Arduino

Plug the Arduino into a USB port or power it with an external adapter.

Monitor the Output:

Upload the code to the Arduino Uno.

Open the serial monitor with a baud rate of 9600 to monitor motor operations.

Project Operation

The motors will alternate between moving forward, stopping, and moving backward as programmed.

Applications

Notes

Ensure all connections are secure and correct to prevent damage to the Arduino or motors.

Adjust PWM values in the code to control motor speed effectively based on your project requirements.
