Auto Light Energy Saver Kit v3
Auto Light Energy Saver Kit v3 – Arduino-Based Energy Saving with AI Voice Command Integration
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
This advanced kit transforms an Arduino UNO into a multi-sensor energy-saving hub that automatically controls lighting based on motion, RFID access, and ambient conditions. Designed for engineers and IoT developers, it also includes all hardware necessary to bridge with a Linux MPU running a Phi-2 quantised LLM — enabling natural language overrides through a Visual Bridge serial protocol. Build a real-world intelligent light management system that cuts consumption in offices, maker spaces, or smart buildings.
What You'll Build
You’ll assemble a permanent, wall-mountable automatic light controller. Dual PIR sensors detect occupancy across zones, an RFID reader grants user-specific lighting profiles, and DHT22 sensors monitor temperature/humidity to adjust behaviour. A 4‑channel relay switches mains loads, while the 0.96‑inch OLED displays diagnostics. The included prototyping boards and soldering tools let you transition the circuit from breadboard to a robust final build inside the enclosure box. When connected to a Linux single‑board computer (not included), the system can accept spoken commands processed by a quantised Phi-2 LLM and translated into Arduino function calls.
What You'll Learn
- Interfacing multiple digital and analog sensors (PIR, DHT22, RFID) with Arduino and managing concurrent event‑driven code.
- Designing safe relay‑switched mains circuits with flyback diodes, decoupling capacitors, and proper power regulation using a buck converter.
- Implementing state‑machine logic for occupancy‑based light control, energy‑saving schedules, and RFID‑linked user preferences.
- Establishing a serial communication bridge (Visual Bridge) to receive commands from an external Linux MPU running a quantised LLM, enabling natural language-controlled automation.

Who This Kit Is For
Engineers pursuing B.Tech ECE/EEE final-year IoT projects, Smart India Hackathon teams building smart‑city energy demonstrators, and early‑career embedded developers prototyping commercial building management systems. Also fits R&D labs in NITs, IITs, and VIT where natural language control of hardware is being explored.
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 QR code on the enclosure to start a conversation with the AI companion fine‑tuned on this kit’s wiring and code. If a trickier issue arises, our WhatsApp support line connects you directly to our engineers.
Do I need a Linux MPU to make the kit work?
No. The Arduino runs fully autonomous lighting logic out of the box. The LLM‑based voice‑control feature is an optional advanced extension and requires a separately purchased Linux board like a Raspberry Pi.
What is the Visual Bridge protocol?
It’s a documented serial communication layer that translates LLM statements into Arduino function calls. We provide a ready‑to‑flash library and wiring guide to connect your Arduino to a Linux host.
Can I use this kit for a college project submission?
Yes. The kit’s documentation includes a structured project report template, circuit diagrams, and block diagrams tailored for academic evaluation by Indian universities.
Energy Saving — Phi-2 quantised LLM on Linux MPU interprets natural language commands and calls STM32 functions via Visual Bridge.
