Bluetooth Control Car/Bot Using HC-05 Bluetooth Module, L298N Motor Driver, and Arduino Uno

This project allows you to control a car or robot wirelessly using a Bluetooth module (HC-05), an Arduino Uno, and an L298N motor driver. The provided Arduino sketch enables the robot to move forward, backward, make sharp turns, and stop based on Bluetooth commands.

Components Used

• Arduino Uno
• HC-05 Bluetooth Module
• L298N Motor Driver
• DC Motors (for the car's movement)
• Chassis, Wheels, and other mechanical components
• Power source (batteries or external power supply)

Wiring Instructions

1. Connect the DC motors to the L298N motor driver.
2. Connect the L298N motor driver to the Arduino Uno.
3. Connect the HC-05 Bluetooth module to the Arduino Uno.
4. Ensure proper power supply to the motors and the Arduino.

Refer to the provided Arduino sketch (BluetoothCarControl.ino) for specific pin connections.

Arduino Sketch Explanation

The Arduino sketch (BluetoothCarControl.ino) is responsible for interpreting Bluetooth commands received via serial communication and controlling the motors accordingly. The code defines functions for moving the car forward, backward, making sharp turns, and stopping.

Getting Started

1. Set up the hardware components as per the wiring instructions.
2. Upload the BluetoothCarControl.ino sketch to your Arduino Uno.
3. Power up the Arduino and ensure the Bluetooth module is paired with a mobile device.

Bluetooth Commands

• 'f': Move forward
• 'b': Move backward
• 'l': Make a sharp left turn
• 'r': Make a sharp right turn
• Any other input: Stop the car

Usage

1. Pair your mobile device with the HC-05 Bluetooth module.
2. Open a serial communication app on your mobile device.
3. Send the corresponding commands to control the car.
