Control an LED with Just Your Finger! | OpenCV + Python + Arduino Gesture Control

Описание: Welcome to RoboRequest – You Ask, We Build!
In today’s tutorial, we’re combining Computer Vision + Python + Arduino to build something really fun — a Gesture Controlled LED! 💡✋

By the end of this video, you’ll be able to turn ON/OFF an LED just by raising your index finger in front of your webcam — no buttons or switches required!

This project is a great next step 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.

🔧 This video covers:

✅ Connecting LED & resistor to Arduino Uno
✅ Uploading Arduino code to listen for ON/OFF commands
✅ Installing Python libraries: OpenCV, MediaPipe, PySerial
✅ Writing the Python code for hand gesture detection
✅ Sending serial data from Python to Arduino
✅ Live demo — Raise your finger → LED turns ON, Lower your finger → LED turns OFF

💡 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

📦 What You Need:
🔌 Arduino Uno + USB cable
💡 1 LED + 220-ohm resistor
🔗 Breadboard & jumper wires
🖥️ Laptop/PC with webcam
🐍 Python 3.9
⚡ Libraries: OpenCV, MediaPipe, PySerial
