Abstract
Notice board is basic essential thing in any institution or organization or public utility places such as bus stops, railway stations or parks. But sending various notices every day is a tedious process. This paper deals with the advanced notice board. It involves an SMS based notice board incorporating the widely used GSM to facilitate the communication of displaying a message on the notice board through a user's mobile phone. Its operation is based on microcontroller AT80C51 programmed in assembly level language. A SIM300 GSM modem is interfaced with a SIM card to the ports of the microcontroller with the assistance of AT orders. At the point when the Subscriber sends a SMS by means of an enrolled number from his cellular telephone, it is gotten by SIM300 GSM modem at the recipient end. SIM300 is appropriately interfaced through a level shifter IC MAX32 to the microcontroller. The informed is gotten into the microcontroller. It is further shown on an electronic notification board which outfitted with LCD show interfaced with chip controlled by a directed force supply from mains supply of 230 volts air conditioning. This anticipate is probed ongoing taking note.
