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: ...
No doubt students learn more when they are mentally and physically engaged in the learning process, regardless of the subject they are studying, and when it comes to STEM education , hands-on experiential learning is an indispensable part of the learning process. In this hands-on activity, we will make a water sprayer using two straws, and experience Bernoulli’s Theorem . Category: Physics Sub Topic: Fluid Pressure Time Required : 20-30 min Difficulty: Easy Things We Need 2 Straws (4 inches each) Insulation Tape Eraser Scissors A glass of water Assembly Pic 1: Cut two insulation tape pieces and attach them to either end of both the straws. Pic 2: While attaching the tape, make sure to leave some space from the end(4-5mm approx). Pic 3 : Tape the 1st straw(I used Green straw as 1st) to the eraser so that the straw is exactly aligned with the edge of the eraser. Pic 4: Next, tape the second straw(I used Orange straw as 2nd) to the edge of th...
