Home Smart Light Switch Kit
Build a Gesture-Controlled Smart Light Switch with Arduino AI Object Detection
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Imagine switching your room light by simply raising your palm. This kit empowers you to build a compact device that uses a camera and a neural network to recognize hand gestures, then drives a relay to control any lamp or appliance. You’ll deploy a pre-trained model on an Arduino microcontroller—no cloud connectivity required—and watch the detected class name appear on an OLED screen. It’s a hands-on deep dive into edge AI for home automation, designed for those ready to move beyond basic Arduino projects.
What You'll Build
You’ll assemble a standalone smart switch that runs a TensorFlow Lite object detection model directly on the Arduino. The OV2640 camera captures real-time frames; when the model identifies a gesture like a fist or an open hand, the system energizes a 5V relay to toggle a connected light. The OLED display shows live inference results and system status. This project creates a working prototype that demonstrates how AI can replace physical switches with intuitive, touch-free control.
What You'll Learn
- Interface an OV2640 camera module with Arduino for continuous image capture and preprocessing.
- Deploy and run a pre-trained object detection model on a microcontroller using TensorFlow Lite for Microcontrollers.
- Safely control AC appliances using a relay module and flyback diodes, understanding isolation and electrical safety.
- Program an OLED display to show real-time class labels and confidence scores from the AI inference.

Who This Kit Is For
This intermediate kit is ideal for B.Tech ECE/EEE students tackling smart home systems for Smart India Hackathon or final-year mini-projects. ATL Tinkering Lab mentors will find it a perfect next step for Class 11–12 innovators who have mastered basic Arduino. Engineering undergraduates at IITs, NITs, VIT, and BITS Pilani will value the real‑world edge AI integration and the opportunity to customize gesture classes for their own automation concepts.
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?
Scan the included QR code to open the AI companion, which walks you through each wiring step and code snippet for this exact kit. You can also send a message on WhatsApp; our engineers typically reply within an hour.
How does the object detection model know which gesture I want to use?
The kit ships with a pre-loaded model that recognizes several basic hand gestures (palm, fist, thumb-up). Using the provided training script, you can film your own custom gestures and retrain the model to match your personal movements—all guided by the companion documentation.
Can I control multiple lights with this kit?
The included relay module offers a single channel, so one lamp or appliance can be switched directly. To control additional lights, you can add more relay modules and modify the Arduino sketch to map different detected classes to different output pins. The code is structured to make this expansion straightforward.
Is soldering required, and is it safe for a beginner?
Yes, you will solder the components onto the PCB prototype board. The kit includes a soldering iron, solder wire, and detailed safety instructions. The AI companion demonstrates proper technique, and the low-voltage side of the circuit is fully isolated from the relay’s AC terminals, so you can practice safely.
