Bluetooth Based Home Automation Electronics Engineering Final Year Project

This project includes Bluetooth (HC-05) module, which is connected to Arduino through UART interface. Three loads connected to Arduino digital pins which are Bulb, LEDs and fan respectively through relays.

WORKING:

User can control loads from Bluetooth Application. Here we have customized app in our mobile. It has buttons on screen. By pressing keys we can control Bulb, fan, and LEDs respectively. All these loads status displayed on 16X2 LCD and in APP screen. Here we used own customized app and we can keep our college name on top of app screen.
