Android mobile Based Smart Wireless Electronic Notice Board

Notice boards play a vital role in offices, in shops and mostly in educational institutions. The events, occasions or any news, which has to be passed to the students, will be written on the notice boards present in every floor in the colleges or schools. The present system is like, a person will be told the news and he has to update this news on all the notice boards present in the college or school. This will be seen mostly during the examination seasons.
The time table or the schedule of the exams has to be given to the students. This will be done by writing the details on the notice boards. But this process consumes a lot time to update the news on all the notice boards and there may be chances that the person responsible may commit some mistakes or he may be absent sometimes. So, this may create disturbances and the entire schedule may be disturbed. To avoid all these, Wireless Notice Board have been designed which completely eliminates the manual work.
Now a day’s so many useful technologies are coming out to make our life style more comfort, luxurious and secure.
Especially in mobile field so many application are being developed to give us more information and entertainment. This project is designed with combination of two latest and most demanding technologies that are Android and Embedded Systems
Android is a Linux based operating system designed primarily for mobile devices and it is a open source .There are so many applications are already developed on Android and many applications are being developed at free of cost for its users .
We can also develop our own customized applications with free of cost or with minimum cost according to our requirements.
In this project we will create an application to update the message on electronic notice board. We have to type the message on our android phone and sends to notice boards using this application then this will be received by controlling section using Blue tooth.
At controlling system side we have Bluetooth module, micro controller and electronic notice board. Whenever this blue tooth module receives new message or notice from android application then it transfers this command to micro controller. Micro controller will update this new notice on electronic notice board.
