Software Controlled Car

This project aims to build a Bluetooth-controlled car using Arduino technology. A smartphone controls the vehicle wirelessly. The main part of the system is the Arduino Uno, which processes signals from the HC-05 Bluetooth module and sends them to the L298 motor driver to control the DC motors. Users can easily move the car forward, backward, left, or right by sending commands through a mobile application. Features: • Wireless Operation – Controlled via smartphone using Bluetooth connectivity. • Cost-Effective – Uses affordable and easily available components. • Multi-Directional Movement – Moves forward, backward, left, and right. • Easy to Use – Simple mobile app interface for real-time control. • Portable Design – Compact and battery-powered for mobility. Requirements: • Hardware:- Arduino UNO, TT Gear Motor, L298 motor driver, Wheels, HC – 05 Bluetooth module, Jumper Wires, Lithium Battery. • Software:- Arduino IDE C/C++, Arduino Bluetooth Controller. Advantages and Disadvantages: • Advantages: - Real-Time Response – Provides smooth and quick movement based on user commands. - Low Cost – Built using inexpensive and easily available components. - Customizable – Can be enhanced with sensors for obstacle avoidance, line following, or automation. • Disadvantages: - Limited Range – Bluetooth control works only within a short distance (about 10 meters). - Low Speed & Power – DC motors and battery power restrict heavy load or highspeed operation. Existing system (feedback): The Arduino Bluetooth-controlled car is a simple, low-cost project that demonstrates wireless control using a smartphone. It provides hands-on learning in Arduino programming, motor control, and Bluetooth communication, while also offering scope for future upgrades like sensors and automation.
