Voice-Controlled Home Automation Kit with Arduino Uno & Bluetooth HC-05

Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.

Speak to your room and the appliances obey. This kit puts you at the center of a custom voice-automation build: an Android app sends spoken commands over Bluetooth to an HC-05 module, the Arduino Uno deciphers keywords like “fan on” or “light off,” and a 4-channel relay module switches actual mains-powered appliances by name. You’ll wire, test, and refine every part of the logic on a single breadboard—no soldering, no scattered tutorials.

What You'll Build

You’ll assemble a voice-activated control panel that listens for Bluetooth commands, drives a 16x2 LCD display (with I2C backpack) to show real-time relay status, and triggers up to four AC appliances through a relay board protected by 1N4007 diodes. The resulting circuit lets you walk in, say a name like “night lamp,” and watch the room respond—all from your own code and wiring.

What You'll Learn

• Interfacing HC-05 Bluetooth module with Arduino for wireless serial command reception
• Configuring a multi-channel relay module and adding flyback diodes for safe switching of inductive loads
• Using I2C communication to drive a 16x2 LCD without consuming digital pins needed for relays
• Developing keyword parsing logic in Arduino to map spoken device names to specific relay channels

Why Buy This Kit Instead of Sourcing Parts Separately

Who This Kit Is For

Ideal for B.Tech ECE, EEE, and CSE students prototyping voice-activated home automation as a mini or major project. If you’re preparing for Smart India Hackathon, refining a final-year IoT solution, or an advanced hobbyist coming from ATL Tinkering Labs and ready to move beyond basic Arduino builds, this kit gives you a complete voice-control system with the components and guidance to make it work.

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.
