✋ Hand Gesture Volume Control

A simple computer vision project that allows you to control your system volume using hand gestures (thumb & index finger distance).
Built with OpenCV and MediaPipe.

🎥 How It Works

• Opens webcam and tracks your hand in real-time
• Detects index fingertip (id=8) and thumb tip (id=4)
• Measures distance between them:
  • Far apart → Volume Up
  • Close together → Volume Down

🛠️ Tech Stack

• OpenCV – Image capture and drawing
• MediaPipe – Hand landmark detection
• PyAutoGUI – Sending volume key presses
