🛠️ How It Works

1. The webcam detects your hand using MediaPipe Hands.
2. It calculates the distance between your thumb tip and index finger tip.
3. The screen brightness is adjusted proportionally based on this distance.
   • Closer fingers = lower brightness
   • Further apart = higher brightness
