Cheap Bluetooth Solution for Smart Controlled Home Devices

The aim of this paper is to build a Bluetooth based system to connect various home devices to mobile devices such as smart phones and tablets. This system will allow users to control their home devices from their mobiles. This project tries to create a cheap solution for such tasks using Bluetooth technology. The home devices are connected to an Arduino microcontroller that is programmed to control various functions. Some of the functions include turning the lights on and off with various levels and changing fan speeds for indoor climate change. The controller itself is connected to an Android operated smart phone and its functions are controlled wirelessly via Bluetooth wireless technology. The phone will communicate with the microcontroller by using an Android mobile application that meets the system interaction requirements with the microcontroller. A code will be sent to the microcontroller to receive commands from the android application to control the devices accordingly.
