Design and Development of Bluetooth Controlled Car Using Bluetooth Module HC-05

The Bluetooth controlled car is an Android mobile phone-controlled electronic device that moves in forward, backward, left, and right directions via an HC-05 Bluetooth module. This project replaces the RF circuit of a toy car with an Arduino UNO microcontroller system, utilizing two DC motors—one for steering and one for movement—controlled through a Bluetooth mobile application. The system demonstrates efficient wireless communication and motor control implementation for autonomous vehicle applications.
