Bluetooth Based Wireless Home Automation System 

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.

FPGA Implementation of Keyboard Learner using Spartan3 FPGA Image processing kit

 The main objective of the KBL project is to provide it’s users an easy and straight-forward way to learn, practice and improve the use of the keyboard in typewriting. The proposed solution for reaching this objective is a clean application, with no unnecessary artwork and with a few options for customizing the user-experience. The Spartan3 FPGA Image Processing Kit  based Keyboard  learner system generates and displays random character codes, with a very small possibility of the code being an actual word. This forces the user to keep his eyes on the screen, and not at the keyboard. If the system would use intelligible words, the user would just read them and switch his eyes to the keyboard to type them. The effect of using this system is that users will start typing faster, and with fewer spelling errors, eventually without even looking to the keys.

When a person or motor vehicle enters a monitored area, PIR motion detectors are commonly used in conjunction with indoor or outdoor to turn on a light in response to a person moving in the field of view monitored by the motion detector. Someone enters secured places, immediately it will send sms for the Corresponding people. The people can understood something happens in host section. At the Same time camera keep on capturing images at the host place and saved into the computer. When the owner in remote place, they got messages to the host section by sms, they log into the host section computer through GPRS and WAP enable mobile, they can view all information of the host section images by mobile phone.
