Auto Light Energy Saver Kit with Arduino Nano — Build a Visitor Logging System That Saves Power

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 kit puts a real-world energy-saving project into the hands of a young maker. Using a passive infrared (PIR) sensor, an Arduino Nano detects when someone enters a room and can turn off unnecessary lights when the space is empty — while a connected buzzer plays a cheerful tune and a 16x2 LCD shows the exact time of the visit. It's a practical lesson in how technology can reduce wasted electricity, all while learning programming and circuit basics.

What You'll Build

You'll assemble a working automatic light controller that reacts to motion. When the PIR sensor picks up a visitor, the LCD displays the date and time (from the DS3231 RTC module) and the piezo buzzer sounds a short melody, creating a friendly alert. The system logs every entry with a timestamp, so you can track when rooms are used — the first step toward intelligent energy management.

What You'll Learn

• How PIR sensors detect body heat and output digital signals
• Connecting an I2C LCD display to Arduino Nano using a backpack module
• Reading time and date from a DS3231 real-time clock (RTC) chip
• Writing Arduino code to combine sensor input, display output, and buzzer control
• Practical wiring using a breadboard and jumper wires

Why Buy This Kit Instead of Sourcing Parts Separately

Who This Kit Is For

This beginner-friendly kit is ideal for students aged 10–12 exploring CBSE science projects, ATL Tinkering Lab activities, or simply curious about automation. It's also a solid hands-on starter for B.Tech ECE freshers who want to move beyond theory and build something functional. No soldering is required — every part plugs into the breadboard.

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.
