Project Title: Bluetooth Control Car

The Bluetooth-Controlled Car project aims to create a remotely operated vehicle through Bluetooth communication. The primary goal is to showcase a practical application of wireless communication and remote control technology. This project combines elements of electronics, robotics, and software development to achieve a tangible and interactive result.

HARDWARE COMPONENTS :

Car Chassis: A customized chassis to accommodate the electronic components.

Motors and Wheels:DC motors for controlling the movement of the car.

Microcontroller:An Arduino board to process incoming signals and control motor actions

Bluetooth Module:A Bluetooth transceiver for wireless communication.(HC05)

Power Supply:Rechargeable batteries to power the entire system.

SOFTWARE COMPONENTS :

Arduino Code Editor: The microcontroller is programmed using Arduino code to interpret Bluetooth signals and control motor actions.

Mobile App:A simple mobile application is developed to send control signals to the car via Bluetooth. NOTE – Name of Application is Bluetooth RC Car Control DIY.
