HC-05 Bluetooth LED Control Kit with Arduino Uno – Your First Wireless Project

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 turning on an LED from across the room using nothing but your smartphone. This kit makes that real – you’ll wire an Arduino Uno with an HC-05 Bluetooth module, link a free Android app, and remotely toggle LEDs with simple text commands. It’s the perfect starting point for anyone who wants to understand wireless control and how everyday IoT devices talk to each other.

What You'll Build

After a couple of hours, you’ll have a working Bluetooth-controlled LED board that responds instantly to commands from your phone. Send “LED1 ON” or “ALL OFF” and watch the lights change. This is your first real wireless project – the same principle behind smart bulbs, remote-controlled toys, and home automation gadgets.

What You'll Learn

• Connect and configure an HC-05 Bluetooth module with Arduino Uno
• Write Arduino code to read serial Bluetooth commands from a mobile app
• Control digital outputs wirelessly and understand basic serial communication
• Debug pairing issues and test data transmission between phone and board
