Control Relays & LEDs with Hand Gestures - Pi 5 Kit
Control Relays & LEDs with Hand Gestures Using This Raspberry Pi 5 Kit
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Replace physical switches and buttons with your hand movements. This kit lets you build a real-time gesture control system that drives relays and LEDs - perfect for touch-free home automation prototypes, interactive exhibits, or accessibility projects. Using a Pi 5 and MediaPipe Hands, the system tracks 21 hand landmarks at 30 fps and translates gestures like a pinch, swipe, or open palm into hardware actions.
What You'll Build
A self-contained gesture-controlled interface running entirely on the Pi 5, no cloud needed. You'll map custom hand signals to relay outputs - turn on a lamp with a closed fist, toggle a fan with a swipe, trigger an LED sequence with an open palm. The system includes programmable logic so you can define multiple gesture-to-action rules, creating a touch-free control panel that responds instantly.
What You'll Learn
- Real-time hand landmark detection using MediaPipe Hands on Raspberry Pi 5
- Interfacing 5V relays and LEDs via GPIO and writing Python scripts to control them
- Designing gesture classification algorithms based on 21-joint coordinates
- Deploying an edge AI pipeline with NVMe SSD for fast inference without internet

Who This Kit Is For
Designed for engineering undergraduates (B.Tech ECE/EEE/CS) working on mini-projects or hackathon submissions like Smart India Hackathon. Also ideal for advanced CBSE Class 12 students exploring computer vision in ATL Tinkering Labs, and for makers from IIT/NIT/VIT/BITS prototyping touchless interfaces for home automation or accessibility.
Built and Backed by Compoden
Every Compoden kit ships with an AI build companion trained on this exact project - accessible via a QR code on the box, with WhatsApp and email backup. We've spent 10 years building projects for makers, schools, and institutions across India. If a part fails because of a manufacturing defect, replace it free within 7 days.
What if I get stuck during the build?
The AI companion walks you through each step, and if you hit a roadblock, you can ping us on WhatsApp for a direct response within hours.
Do I need prior experience with Python or computer vision?
Basic Python helps, but the AI companion explains every script and gesture logic; you'll learn as you build.
Can I add more relays or different sensors later?
Yes, the GPIO header and Python scripts are fully extensible - you can integrate additional relays, sensors, or even a display once you complete the core project.
Does the gesture recognition work without internet?
Absolutely. MediaPipe runs entirely on the Pi 5 using the NVMe SSD, so all processing happens locally with no cloud dependency.
MediaPipe Hands tracks 21 hand landmarks in real time on Pi 5 - map gestures to relay and LED outputs.
