Hand Tracking Controlled Servo

Control a servo motor in real time using hand tracking with MediaPipe and OpenCV. The servo angle follows the horizontal position of your index finger.

Overview

• Uses your webcam to detect a hand.
• Tracks the X-position of your index finger.
• Converts the position into a servo angle (0°–180°).
• Sends the angle to an Arduino via serial communication.

Components

• Arduino Uno
• Servo Motor

Prerequisites

Python (3.9 - 3.12)
