In this tutorial to learn the Arduino based Home Automation will enable the user to use a Home Automation System based on Bluetooth Connectivity. The user commands over Android Mobile will be obtained by Mobile Bluetooth. The Microcontroller has an interface with this Bluetooth. The system status is displayed through the LCD display, along with the voice. Bluetooth Home Automation system, for controlling all your electrical appliances by using Android application.
The system works only with associated anroid app.
