Bluetooth Controlled Car using Arduino

The Bluetooth Controlled Car project is a fun and educational robotics project that allows users to control a small robotic car wirelessly using a smartphone via Bluetooth. It uses an Arduino Uno, Bluetooth module (HC-05), motor driver (L298N), and DC motors to control the car’s movement in different directions.

The car receives commands from a smartphone through a Bluetooth terminal or custom Android app. These commands are transmitted to the HC-05 Bluetooth module, which passes them to the Arduino Uno. Based on the received signals (like ‘F’ for forward, ‘B’ for backward, ‘L’ for left, and ‘R’ for right), the Arduino controls the L298N motor driver, which drives the motors accordingly.

This project introduces basic concepts of robotics, motor control, wireless communication, and mobile interface integration. It can be further upgraded by adding sensors for obstacle detection, line following, or GPS modules for autonomous navigation.
