Wireless Multipoint Digi Board Using Raspberry PI

Abstract

The importance of notice board in every academic is well known to us. Wireless multipoint Digi board is an electronic wireless notice board that can be used to display various information in public places and institutions. The notice board we have proposed in this module works on a raspberian platform which is powered by ARM1176JZF-S processor which acts as the heart of the system. The Raspberry Pi of model B is employed for this purpose. Transfer of information is employed by using Wi-Fi technology. The information created in the database of the college website are transferred to the main server to be displayed in the notice board. Information can also be given directly from the main server to the notice board. The server which is password protected transfersthe message through Wi-Fi module to the Raspberry Pi, which displays the message in the LCD display attached to it. The server is provided with an EEPROM to store the messages which can be referred later when needed. The messages are displayed in a scrolling fashion which prevents overlapping of new message with the previous message. Herein we have proposed to transform our college notice board which is being manually operated into digitalized wireless notice board.
