Arduino Bluetooth Car

A voice-controlled car with Arduino and Bluetooth capabilities, enhanced with obstacle detection and RFID scanning.

Project Overview

This project involves building a Bluetooth-controlled car using an Arduino Uno board, allowing voice commands via a Bluetooth module. The car is equipped with obstacle detection using ultrasonic sensors and additional modules for enhanced functionality.

The primary objectives of the project were:

Designing and programming a car controlled via Bluetooth and voice commands.
Integrating ultrasonic sensors for obstacle detection.
Adding modules such as RFID scanners and LCD displays for extended features.
Optimizing the Arduino code to control motors and sensors effectively.

Key Features

Bluetooth Control: Integrated HC-06 Bluetooth module to receive and execute commands from a smartphone app.
Obstacle Detection: Used an HC-SR04 ultrasonic sensor to detect obstacles and navigate safely.
Motor Driver: Configured L298N motor driver to control the speed and direction of two DC motors.
Voice Commands: Utilized a mobile app to translate voice commands into Bluetooth signals, controlling the car's movements.
RFID Scanning: Added an RFID scanner module to read tags and implement secure access or identification features.
LCD Display: Incorporated an LCD screen to display real-time information like direction, speed, and obstacles.
