Building Obstacle Avoiding Robot Arduino using 3 Ultrasonic Sensors

🤖 Welcome back to Lee DIY's Corner!

In this video, we’re building an *Arduino-based Obstacle Avoiding Robot* using *3 Ultrasonic sensors* for better environmental awareness.

💡 How it works:
• The front sensor detects objects directly ahead.
• The left and right sensors check side distances.
• Based on the readings, the robot chooses the best path to avoid obstacles — all in real-time!

Perfect for beginners learning about distance sensing, decision logic, and robot navigation.
