The system consists of a chassis, DC motors, motor driver, battery, microcontroller, and a wireless communication module. The controller transmits commands to the receiver, which controls the movement of the car in different directions, including forward, reverse, left, and right. The main objective of this project is to demonstrate the integration of electronics, embedded systems, and wireless communication in a practical application. The RC car offers reliable performance, ease of operation, and low power consumption, making it suitable for educational, research, and hobby purposes. This project also provides a foundation for future enhancements such as obstacle avoidance, autonomous navigation, GPS tracking, and IoT-based remote monitoring
