🚗 Arduino Bluetooth Controlled Car

📌 Overview

This project makes a Bluetooth-controlled car using Arduino and the HC-05 Bluetooth module.
You can control the car via a smartphone Bluetooth terminal app.

• F → Forward
• B → Backward
• L → Left
• R → Right
• S → Stop

🛠️ Hardware Required

• Arduino Uno/Nano
• HC-05 Bluetooth Module
• L293D Motor Driver Shield (Adafruit AFMotor Library)
• 4 DC Motors + Robot chassis + Wheels
• Battery pack (6–12V)

---

🔌 Wiring

• HC-05 → Arduino

  • VCC → 5V
  • GND → GND
  • TX → RX (D0)
  • RX → TX (D1, use voltage divider)

• Motors → Connected via Motor Driver Shield (M1, M2, M3, M4)

▶️ Usage

1. Install AFMotor library from Arduino IDE Library Manager.
2. Upload the code to Arduino.
3. Pair smartphone with HC-05 (1234 or 0000 as password).
4. Open a Bluetooth terminal app and send commands: F, B, L, R, S.
5. Car moves accordingly.
