Digital Electronics Notice Board is used in public utility places like institutions, organizations, college campus, railway stations, etc. Nowadays, displaying various data on paper notice boards has become difficult and time-consuming. The idea behind the proposed system is to deliver a simple but dependable and constant system to the users, which they could use for putting up important notice and notification on LCD display and the user can simply send a message which will be displayed on LCD display. The projected system allows people to convey notice data on a digital notice board using their mobile phones. The system uses LPC 2148 microcontroller based on 32-bit ARM, a GSM SIM 900 module and a user interface for the android application. The device can work anywhere where mobile network connectivity is available. [ABSTRACT FROM AUTHOR]
