ESP8266 Motor Driver Module Project

Project Overview

This project demonstrates how to control a motor using an ESP8266 microcontroller and an L298N motor driver module. The setup allows you to control the direction and speed of a DC motor, making it suitable for various robotics and automation applications.

Components Needed

• ESP8266 Microcontroller
• L298N Motor Driver Module
• DC Motor
• Jumper Wires
• Power Supply for Motor

Circuit Setup

1. Connecting the Motor Driver Module to ESP8266:
   • Connect IN1 of the L298N module to GPIO pin D1 on the ESP8266.
   • Connect IN2 of the L298N module to GPIO pin D2 on the ESP8266.
   • Connect ENABLE (EN1) of the L298N module to GPIO pin D3 on the ESP8266 for PWM speed control.
   • Connect the motor terminals to the output terminals of the L298N module.
   • Ensure proper power (VCC) and ground (GND) connections between the ESP8266, L298N module, and the motor's power supply.

Instructions

1. Setup:

   • 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. Operation:

   • After uploading the code, the motor will run in one direction for 2 seconds, then switch to the opposite direction for 2 seconds, and then stop for 1 second.
   • The cycle will repeat, demonstrating bidirectional control and speed adjustment of the motor.

Applications

• Robotics: Control motors for robot movement.
• Automation: Use in conveyor belts or other automated systems.
• DIY Projects: Build projects requiring precise motor control, such as RC cars or automated doors.

Notes

• Motor Speed: The speed of the motor can be adjusted by changing the value in the analogWrite(motorEnable, 255); function. The value ranges from 0 (stop) to 255 (full speed).
• Direction Control: The motor direction is controlled by the states of IN1 and IN2 pins. Reversing their states changes the motor's direction.
• Power Supply: Ensure the motor's power supply matches its voltage and current requirements.
