Technology advancements have made possible the implementation of embedded systems within home appliances. This has added new capabilities and features, however, most of the time, the implementations are proprietary and networking is not always possible. Yet there is an increasing demand for smart homes, where appliances react automatically to changing environmental conditions and can be easily controlled through one common device. This paper presents a possible solution whereby the user controls devices by employing a central Field Programmable Gate Array (FPGA) controller to which the devices and sensors are interfaced. Control is communicated to the FPGA from a mobile phone through its Bluetooth interface. This results in a simple, cost effective, and flexible system, making it a good candidate for future smart home solutions.
The Bluetooth wireless technology is set to revolutionize the way people perceive digital devices in our homes and ofﬁce environment. Now they are no longer just the individual devices; instead, with the embedded Bluetooth technology, they form a network in which appliances can communicate with each other. This wireless technology is especially useful in home environment, where there exists hardly any infrastructure to interconnect intelligent appliances. It could be suitably used for home automation in a cost-effective manner. Operating over unlicensed, universally available frequency of 2.4 GHz, it can link digital devices within a range of 10 m (expandable to 100 m, by increasing the transmitted power) at the speed of 1 Mbps. Building upon this theme; we propose a home automation system based on Bluetooth. technology There are certain issues involved in the design of a home automation system. The system should be scalable, so that new device can easily be integrated into it. It should provide a user-friendly interface on the host side, so that the devices can be setup, monitored and controlled. The interface should also provide some diagnostic services so those problems with the system, if any, can be tracked down. The overall system should be fast enough to realize the true power of wireless technology. It should also be cost effective in order to justify its application in home automation.
The system developed consists of android mobile phone and a FPGA based Door Lock open/close system and relay on/off to control electrical Appliance, that is able to communicate with the host through the Bluetooth link.

The Bluetooth home automation mobile software module provides two main services to the users, namely:
- Device Registration
- Device Control
Hardware design and development
A Door Lock open/close system and relay on/off to control electrical Appliance circuitry has been developed to demonstrate the feasibility and effectiveness of the application. The hardware interface component of the Bluetooth based home automation system consists of a FPGA with stepper motor, relay interface and an RS232 link between the FPGA and the Bluetooth.
