Once, I wanted to control my home lights using my Mobile phone. I searched on google, Youtube for help but these biggest platform disappointed me due to not a proper guidance.

Then, I decided to learn all this and helps to learn you and others in this world.

So, here I am going to explain you How to Control Lights using Mobile Phone.

I am going to explain you through a video because you can see Step by Step physical process in video.

Wireless Control: Bluetooth Home Automation

The Bluetooth Relay Dashboard is the quintessential maker project. It serves as the perfect bridge between writing smartphone software and controlling physical, high-voltage hardware.

Serial Communication Protocol

The core of this project is understanding UART Serial Communication.

  1. The App: You use a custom Android App (often built with MIT App Inventor) or a generic Bluetooth Terminal.
  2. The Button: When you press the "Lamp ON" button on your phone, the app sends a single character over Bluetooth: the letter 'A'.
  3. The Receiver: The HC-05 module passes the 'A' to the Arduino's RX pin.
  4. The Switch: The Arduino code uses a switch/case statement. case 'A': digitalWrite(relay1, HIGH); break;.

Hardware Components

  • Arduino Uno/Nano: The command center.
  • HC-05 or HC-06 Bluetooth Module: The wireless link.
  • 4-Channel 5V Relay Module: Perfect for controlling up to 4 separate appliances.
  • Jumper wires and Breadboard.

Safety Warning

When connecting the relay to main 110V/220V AC wiring, ensure the Arduino is completely unplugged from your PC. Use proper junction boxes, secure your screw terminals tightly, and always respect high-voltage safety practices!
