This project presents a Wireless RF Based Synchronization of Multiple DC Motors using RF communication and PWM control. One motor act as the master motor, while the other motors operate as slave motors and automatically synchronize their speed with the master motor. IR sensors provide RPM feedback to the microcontroller, and the synchronized speed is displayed on an LCD. A keypad is used to set the desired speed of the master motor. The system reduces speed errors, improves efficiency, and is suitable for industrial applications such as textile mills, conveyor systems, steel plants, and paper industries where multiple motors must operate at the same speed.            

The main features of this project are:  

1. Real time DC motor speed setting.
2. Display of DC motor speed on LCD.
3. Contact less speed monitoring.
4. Dynamic speed setting feature.
5. PWM based speed adjustment.
