(This page includes the complete code and circuit diagram of Home Automation Project.)
App used in this Project: https://play.google.com/store/apps/details?id=com.himanshu.ArduinoAutomation
Note: In Circuit diagram I have just connected 2 Channel Relay and 2 Appliances but according to code you can connect 9 Relay at digital pins 4, 5, 6, 7, 8, 9, 10, 11 & 12. You can increase the number of appliances according to you, there will be no need of changing anything in the code.
For more information regarding the Project you can watch this video: https://youtu.be/i4A1lT43w5g
- Project Components:
- Arduino UNO Board:
- 2 Channel Relay Module:
- Bluetooth Module HC-05:
- Half Breadboard:
- Jumper Wires:

Codes for this project..
(Codes are given below. Just copy and paste in ardiuno ide. or click here for codes. )
========================================================
* This code is for ON/OFF tab of Arduino Automation App.
* The code is campatible for all Arduino Boards
* You can use the digiatl pins from 4 to 12 to connect the Relay Module
* Connections of Arduino and Bluetooth Module HC-05 for this Code:
* Arduino | Bluetooth Module (HC-05)
* 3 | RX
* 2 | TX
* 5V | 5V
* GND | GND
