Control a Servo Motor with Just Your Palm! (Python + Arduino Project)

Welcome to RoboRequest – You Ask, We Build!
In today’s tutorial, we’re combining Computer Vision + Python + Arduino to build something super fun — a Palm Controlled Servo Motor! 🤚⚙️

By the end of this video, you’ll be able to control the angle of a servo motor (0° to 180°) just by moving your palm closer or farther from your webcam — no buttons, no joysticks, just pure gesture control!

This project is a perfect continuation if you’ve already followed our first video on installing Python, VS Code, and setting up libraries. Now, we’ll bring it all together with OpenCV, MediaPipe, and PySerial to control real hardware with your hand.

🔧 This video covers:
✅ Connecting a servo motor to Arduino Uno
✅ Uploading Arduino code to receive angles from Python
✅ Installing Python libraries: OpenCV, MediaPipe, PySerial
✅ Writing Python code to detect palm position & estimate distance
✅ Mapping palm distance to servo angle (0°–180°)
✅ Live demo — Move your palm → Servo follows smoothly!

💡 Ideal for:

Students learning Arduino + Python integration

Beginners in AI & Computer Vision

Robotics enthusiasts experimenting with gesture control

Anyone curious about real-time hand tracking
