Earthquake Detector using Arduino and Vibration Sensor

Bluetooth Controlled Car using Arduino

The Bluetooth Controlled Car is a beginner-friendly robotics project that allows you to control a small car using a smartphone via Bluetooth. It uses an Arduino Uno, HC-05 Bluetooth module, L298N motor driver, and DC motors for movement.

Commands are sent from a mobile app (or Bluetooth terminal) to the HC-05, which communicates with the Arduino. The Arduino interprets these commands and instructs the motor driver to move the car forward, backward, left, or right accordingly.

This project is perfect for learning wireless communication, motor control, and basic robotics. It can be upgraded by adding sensors for obstacle avoidance or automation features.
