A Beginner-Friendly STEAM Project Using Raspberry Pi, Computer Vision & Python Imagine This for a Moment… You walk into a room. Instead of searching for a switch, you simply raise your finger — and the light turns on. Lower your finger — the light turns off. No buttons. No physical contact. Just vision, code, and a bit of electronics . This is not science fiction. This is exactly what your students will build in this project. Welcome to a hands-on STEAM activity where computer vision meets electronics , designed especially for beginners who are learning Raspberry Pi , Python , and real-world problem solving . In real life, gesture control is already everywhere: Automatic doors Touch-free switches Smart TVs Motion-controlled games Assistive technology for people with limited mobility This project introduces you to how those systems actually work , not through theory slides — but by building one themselves . By the end of this activity, students will: ...
