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 common notice 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 at the faculty in order to display latest information.  The 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. 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 .  

You can see the notice boards being used specially at offices and public places to display important news and notices. To make the notice boards easy to use and more technical advance, I have used this prototype of wireless notice board where we can display the message by simply sending the message through your cell phone. These display systems are very accurate and easy to control and cheaply available and the most important thing is that they can be operated on low Voltage (Up to 12 Voltage).A GSM module is used here for the wireless notice board to send the information or message to display. The main aim of this project is to save time and provide information urgently on display for the customers.
