Bluetooth-Home-Automation

Description

A solution to control home appliances using a Bluetooth device (an Android smartphone).

This repository consists of source code for an Android app as well as Arduino configuration.

Requirements

Before you begin, ensure you have the following:

1. Arduino development board
2. HC-05 or HC-06 Bluetooth module
3. 5V DC / 220V AC relays
4. Android Bluetooth device
5. Connecting wires.

Steps to set up Arduino

Complete the following steps to set up Arduino. You can use the Arduino documentation for reference:

• Upload the Arduino code in the repository root for the Arduino controller
• Connect PIN 11(TX) pin of Arduino to RX pin of HC-05
• Connect PIN 10(RX) pin of Arduino to TX pin of HC-05
• Connect 5V of Arduino to V_in of HC-05 and V_cc of relays
• Connect GND of Arduino to GND of HC-05 and GND of relays
• Connect IN of relay to PIN 13 of Arduino board(you are free to use any pin and also multiple pins, just update the arduino code)
• Connect 220V AC Line to Pole and Load(appliance) to NO of the relay
• Power the Arduino board and you're ready to use. Refer to circuit diagram for setup:

How to use

• Build and install the app on an Android Bluetooth device.
• Turn Bluetooth ON and pair with HC-05 using the default passcode '1234' (Feel free to change this).
• Open the app, click on select controller and select the HC-05
• Use ON/OFF buttons to control the appliance.
