‘Smart LED Notice Board using Bluetooth Device’ is a model for displaying notices/messages at places that require real-time noticing, by sending messages in the form of SMS through mobile. The project aims to develop a moving sign board which empowers the user to change the scrolling message using SMS service instantaneously unlike a deskbound device such as PC or laptop. The user can update it even from a remote distant. The SMS is deleted from the APP each time it is read, thus making room for the next SMS. This document 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 SMS 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, public places, malls or big buildings to enhance the security system and also make awareness of the emergency situations and avoid many dangers. Using Bluetooth module display the message onto the display board.
