If you want to create home automation Arduino project? Want to control the lights fan any other
appliances via phone. Home automation will show you how to make home automation
project using smartphone.For making this project you does not need programming
knowledge.Everything is free only you need purchase hardware.This project is based on
Bluetooth technology.
 
 

How to make home automation Arduino project

Steps:-1

  1. Hardware:-

  • Arduino Uno – at-mega 328
  • Bluetooth transceiver – HC05
  • Jumper ware – male to female and female to male
  • 9V battery or 5V mobile charger adapter
 

      2. Software:-

 
 

 Step:-2  Circuit diagram
