Working Principle:

The microcontroller is used to control the devices. An embedded c program is pre written into the microcontroller which is programmed according to our need. The microcontroller is then interfaced with the relays. Android App will send a serial data to the microcontroller via the Bluetooth interface. The microcontroller does the task assigned to it. The part of Android GUI is solely to provide user interface which when interrupted sends data to microcontroller.

Software Requirements:

LANGUAGE-Embedded C.
TOOLS: Keil uVision3
Android
