Presently almost all electronic notice boards are designed using wired system.One of the drawbacks of the design is the system is inflexible in term of placement. The commonnotice board cannot be placed anywhere because of the messy wire. The aim of this project is to develop a wireless notice board that will be used atthe faculty in order to display latest information.
This wireless notice board project mainly focuses on transmission of textual data through air interface by the use of GSM through asynchronous serial communication. The data will be processed by the microcontroller on both ends. The data will be displayed on LCD only after entering unique pass key.
Actually what happens is, sending SMS through phone has become very popular and if we can use this SMS to control devices and in displaying data. It is possible to receive or decode the SMS globally by using GSM, by the any part of world we can control and display data on LCD board.
In this project we not only send the data but send the data with pass code also. Which enables us to prevent the unauthorized use of LCD display board and only the person who have pass code can have access to LCD board
