The work presented in this paper deals with the wireless notice board design using bluetooth technologies. This project deals with an innovative rather an interesting manner of intimating the message to the people using a wireless electronic display board which is synchronized using the Bluetooth technology. This will help us in passing any message almost immediately without any delay just by sending a SMS or voice message which is better and more reliable than the old traditional way of passing the message on notice board. This proposed technology can be used in colleges, many public places, malls or big buildings to enhance the security system and also create awareness of the emergency situations and avoid many dangers. Using Bluetooth module message can be displayed on the LCD display board and using GSM module SMS or voice message can be sent to the Bluetooth module. The Electronic notice board is wireless and needs no wires for displaying the information on the LCD Display. It is very easy to operate and consumes less power. The circuit of the wireless notice board is portable. The work presented here is the mini-project work of the second semester engineering students of electronics & communication engineering department of Dayananda Sagar College of Engg., Bangalore, Karnataka.
