Arduino Bluetooth Car

A Bluetooth and Serial Monitor controlled Arduino car with motor control, obstacle detection, and hands-on embedded systems design.

Description

This is an Arduino-based car project controlled through both a Bluetooth app using an HC-05 module and the Arduino IDE Serial Monitor. The car uses an L293D motor driver to control four DC motors for forward, backward, left, and right movement.

The system also includes an ultrasonic sensor and a servo motor for automatic obstacle detection and avoidance, allowing the car to navigate safely around objects.
