Bluetooth Controlled Robot Car

Introduction

Control a robot car using Bluetooth. This project leverages the HC-05 Bluetooth module and UART communication to receive commands from a device, such as a smartphone or PC, directing the car's movement.

Requirements

• LaunchPad
• Robot car with two DC motors
• 6+ AA batteries
• HC-05 Bluetooth module
• Serial terminal application (e.g., tera term, Putty)
• Smartphone/Laptop with Bluetooth capability

Setup & Configuration

Bluetooth Module

• Connection: Connect the HC-05 Bluetooth module to the microcontroller using the provided pin configuration.
• Configuration: Use AT commands to set up the Bluetooth module. Ensure it's paired with your device.

Robot Car

• Ensure the car is in data mode for communication.
• Configure the car to respond to specific Bluetooth commands.

Usage

Use a Bluetooth terminal application to send commands:

• F: Move Forward (Green LED on)
• B: Reverse (Blue LED on)
• L: Turn Left (Yellow LED on)
• R: Turn Right (Purple LED on)
• S: Stop (All LEDs off)
• U: Increase Speed
• D: Decrease Speed
