Abstract

Announcement Board is a primary thing in schools and colleges. When every announcement need to be conveyed to all, a separate person is required to take care of this notices display. In the case of digital displays if they want to change the message or style an operator have to go there. The problem of existed announcement board is that it requires manual operation and hard to handle. This project is mainly about a design and implementation of announcement board, which can send messages by using GSM. This project is based on displaying information on LED matrix board by the any part of world through GSM network, which can function to control any message board globally from different location. Before the information is displayed, the buzzer and LED will turn on to alert people’s attention about the upcoming announcement. The data are processed by microcontroller. The data that is sent are displayed on LED matrix board. As this will be the announcement board that will be used in school and colleges, so it will be easier for teachers and lecturers to convey the information. Whenever a message needs to be conveyed, they just need to SMS the message to the SIM in GSM Modem, which is connected, to the Announcement Board and the buzzer will be on before the announcement display on the board. So, this any lecturer or teacher can SMS it the message to be conveyed like urgent gathering of class students at seminar hall. Some analyses have been successfully done in order to find out the system achievement in displaying the announcement through wireless technology. The analyses that have been done are based on the location SMS function, the total character to be displayed and the speed of the scrolling text. In conclusion, the system have successfully developed and analyzed through the function that can accept the sent SMS from mobile phone, notify by switching on the buzzer and then display on the LED matrix board.
