This project demonstrates a secure, Bluetooth-controlled smart car built using Arduino. It features biometric authentication with a fingerprint sensor, ensuring only authorized users can control the car via Bluetooth.
-
🔒 Fingerprint Authentication
Only authorized fingerprints can unlock the car controls. -
📱 Bluetooth Control
Control the car remotely using a smartphone app (via HC-05 Bluetooth module). -
⚙️ Motor Driver Integration
Use of L298N Motor Driver for controlling car movement (forward, backward, left, right, stop). -
💡 Secure Startup
The car remains locked until a valid fingerprint is scanned.
- Arduino UNO or Nano
- Fingerprint Sensor (R307 or similar)
- HC-05 Bluetooth Module
- L298N Motor Driver
- 2 DC Motors with Wheels
- 9V Battery or suitable power source
- Chassis, jumper wires, breadboard, etc.
| Component | Arduino Pin |
|---|---|
| Fingerprint TX | Pin 10 |
| Fingerprint RX | Pin 11 |
| HC-05 TX | Pin 0 (RX) |
| HC-05 RX | Pin 1 (TX) |
| L293D Motor driver | |

- System powers on and waits for valid fingerprint scan.
- Once authenticated, it enables Bluetooth command control.
- User sends directional commands via Bluetooth.
- Car responds accordingly using motor driver.
