DC MOTOR SPEED AND DIRECTION CONTROL

Abstract: This paper presents a wireless control system for DC motors utilizing an ESP8266 Wi-Fi module and an Arduino In the field of electronics and control systems, it is often required to control the speed of a DC motor with precision. One of the popular ways to achieve this is by using an Arduino Uno board and PWM (Pulse Width Modulation) signal to control the motor speed. This project implements a wireless DC motor controller using Arduino and an ESP8266 module. It enables remote control of motor speed and direction via a mobile app, integrating Arduino for motor interfacing and ESP8266 for communication. The system offers real-time responsiveness and reliability, ideal for applications in robotics and IoT requiring precise motor control. Experimental validation confirms its effectiveness in varied operational contexts.
