The project is an electronic notice board that is controlled by an android device and displays message on it. Traditionally, there were notice boards where any information or notice had to be stick daily. This becomes tedious and requires daily maintenance.
The project overcomes this problem by introducing an electronic display notice board interfaced to an android device through Bluetooth connectivity. The Bluetooth receives the message from the android device that is sent to a microcontroller of 8051 family. The microcontroller displays the message on a LCD screen. This project can be used in colleges, offices, railway stations or airports for displaying any information.
