🚗🔵 Arduino Bluetooth Controlled Smart Car Project 🔵🚗

Excited to share my latest electronics project! 🎉

I built a Bluetooth-controlled robotic car using:
✅ Arduino Uno
✅ HC-05 Bluetooth Module
✅ L298N Motor Driver
✅ DC Motors
✅ Android Mobile App (Remote Control)

The car is controlled wirelessly from a smartphone, allowing it to move forward, backward, left, right, and stop in real time through a Bluetooth connection.

This project helped me improve my skills in:
🔹 Arduino Programming
🔹 Embedded Systems
🔹 Bluetooth Communication
🔹 Motor Control
🔹 Electronics & Robotics

More exciting IoT and robotics projects coming soon! 🚀
