Bluetooth Controlled Car

Project Overview

This project is a Bluetooth-controlled robot car designed and developed using the Arduino Uno microcontroller. The central objective was to create a mobile-based wireless control system that allows users to seamlessly navigate the car's movement—Forward, Backward, Left, and Right—without physical tethering.

The system utilizes the HC-05 Bluetooth module for two-way communication with a smartphone application, processing real-time control signals. To manage the physical components, an L298N motor driver was implemented to effectively handle power delivery to the dual DC motors. This project served as a comprehensive exploration of both embedded software development and hardware integration protocols.

Key Deliverables

• Achieved a stable 10-meter wireless control range.
• Designed a low-latency signal processing logic for real-time response.
• Implemented battery-efficient power routing for extended runtime.
• Prototyped a scalable framework for future sensor integration (e.g., obstacle avoidance).
