Multi-Room Alarm Button Kit – Bring Home Automation to Your Fingertips with Arduino Uno

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 a single buzzer that alerts you exactly which room needs attention – just like a nurse call system, but built with your own hands. This kit puts that idea on your workbench: three pushbuttons located in different rooms, one shared active buzzer, and a 16×2 LCD screen that instantly shows “Bedroom,” “Kitchen,” or “Living Room” when a button is pressed. It’s a practical introduction to home automation, perfectly sized for a bedroom-to-living-room experiment or a school technology demonstration.

What You'll Build

You’ll assemble a three-zone alert system on a single breadboard. Each tactile button represents a room; pressing any one immediately activates the buzzer and displays a custom message on the LCD. The wiring uses pull-down resistors for stable readings, and the I2C backpack simplifies the LCD connection to just four wires. When finished, you’ll have a working prototype that can be mounted in a cardboard house model or expanded with longer wires for real inter-room testing.

What You'll Learn

• Solderless breadboard prototyping with real components
• Reading multiple digital inputs from tactile buttons with pull-down resistors
• Programming the Arduino Uno to detect which button was pressed and trigger outputs accordingly
• Controlling a 16×2 LCD via I2C to display dynamic room names

Why Buy This Kit Instead of Sourcing Parts Separately

Who This Kit Is For

Designed for young makers aged 5–15 (adult supervision required), this kit is a natural fit for ATL Tinkering Labs, CBSE Class 8–10 science activity periods, and school electronics clubs. It also serves first-year B.Tech ECE students at IIT, NIT, VIT, or BITS who need a tangible demo of input/output programming. Hobbyists looking for a weekend project to teach kids about home automation will appreciate the guided, frustration-free build.

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.
