Light On & off with smartphone using Arduino UNO

Hello guys In this article I am going to tell you how you can make an easy smartphone-controlled Home Automation system. It is a very easy way to build this project.



You need hardware to make:- 

  1. Arduino Uno
  2. HC -05 Bluetooth Module
  3. Single-Channel Relay module
  4. AC bulb, Wire, Plug
  5. 9-volt battery Or AC to DC power supply

You need software to Run:-

  1. Arduino IDE ( for upload code to Arduino UNO)
  2. Project  code ( Download Arduino code from here)
  3. Remote XY library ( you have to install remote xy library in Arduino IDE)
  4. Download Remote Xy android app from play store

Connection

  • Arduino Digital pin 3 to HC 05 Bluetooth module RX
  • Arduino Digital pin 2 to HC 05 Bluetooth module TX
  • Arduino  5v to HC 05 Bluetooth module VCC
  • Arduino  gnd to HC 05 Bluetooth module gnd

  • Arduino Digital pin 13 to Relay module signal in pin
  • Arduino vin to Relay module vcc pin
  • Arduino gnd to Relay module gnd pin


Important :- Dont touch the circuit when Ac is connected
