ESP32 H-Bridge Module Project

This project demonstrates how to control a DC motor using an H-Bridge module with an ESP32 microcontroller. H-Bridge modules allow bidirectional control of motors, enabling them to rotate in both clockwise and counterclockwise directions.

Components Needed

• ESP32 Microcontroller
• H-Bridge Motor Driver Module (e.g., L298N)
• DC Motor
• Jumper Wires
• Breadboard
• Power Supply (suitable for the motor)

Circuit Setup

1.Connecting the H-Bridge Module to ESP32:

Connect the IN1 pin of the H-Bridge module to GPIO pin 12 on the ESP32.

Connect the IN2 pin of the H-Bridge module to GPIO pin 14 on the ESP32.

Connect the motor terminals to the OUT1 and OUT2 of the H-Bridge module.

Connect the power supply (e.g., 9V battery) to the H-Bridge module to power the motor.

Instructions

1.setup

Initialize GPIO pins connected to the H-Bridge module (IN1 and IN2) as outputs using pinMode() in the setup() function.

Set the initial direction of the motor by setting IN1 and IN2 accordingly (e.g., clockwise or counterclockwise).

2.operation:

In the loop() function:

• Rotate the motor clockwise by setting IN1 high and IN2 low for 2 seconds using digitalWrite() and delay().
• Stop the motor by setting both IN1 and IN2 low for 1 second.
• Rotate the motor counterclockwise by setting IN1 low and IN2 high for 2 seconds.
• Stop the motor again for 1 second.
• Repeat this cycle to create a continuous back-and-forth motion of the motor.

3.considerations:

Motor Power: Ensure the power supply connected to the H-Bridge module matches the motor's voltage and current requirements.

H-Bridge Module: Verify the H-Bridge module's specifications and connections to ensure correct motor control.

Applications

robotics: Control movement of robot wheels or arms.

automation: Drive conveyor belts or automated doors.

DIY Projects: Build custom motorized devices with bidirectional motor control.

Notes

Motor Control: The H-Bridge module allows for bidirectional control of DC motors, essential for many robotics and automation applications.

timing: Adjust the delay() periods to modify motor rotation duration and stopping intervals based on specific project requirements.
