ESP8266 H-Bridge Module Project

This project demonstrates how to control a DC motor using an H-Bridge module with an ESP8266 microcontroller. It allows the motor to rotate forward and backward by switching the polarity of its connections using the H-Bridge.

Components Needed

Circuit Diagram

Circuit Setup

1.Connecting the H-Bridge Module to ESP8266:

motorPin1 (IN1): Connect to a GPIO pin on ESP8266 (e.g., D1).

motorPin2 (IN2): Connect to another GPIO pin on ESP8266 (e.g., D2).

+5V and GND: Connect to the respective +5V and GND pins on ESP8266.

Motor Connections: Connect the DC motor to the output terminals of the H-Bridge module (check the module's datasheet for exact pin configurations).

Instructions

1.Code Upload:

Open the Arduino IDE with ESP8266 board support installed.

Create a new sketch and paste the provided Arduino code.

Connect the ESP8266 to your computer, select the appropriate board and port from the Tools menu.

Upload the code to the ESP8266.

2.Testing:

After uploading the code, the motor will rotate forward for 2 seconds and then backward for 2 seconds continuously.

Ensure the motor responds correctly to the forward and backward commands.

Code Explanation

The code defines two GPIO pins (motorPin1 and motorPin2) connected to the H-Bridge module for controlling the direction of the DC motor.

Two functions, motorForward() and motorBackward(), are used to set the appropriate states (HIGH and LOW) to the motor control pins to rotate the motor forward and backward, respectively.

Applications

Robotics Projects: Control motors for movement in robotic applications.

automation: Use in projects where precise motor control and direction switching are required.

DIY Vehicles: Implement in small vehicles or drones for directional control.

Notes

Motor Specifications: Ensure the H-Bridge module and the power supply can handle the current and voltage requirements of your DC motor.

safety: Avoid connecting the motor directly to the ESP8266; always use the H-Bridge module to isolate and control the motor.

H-Bridge Selection: Choose an H-Bridge module suitable for your motor's voltage and current ratings.
