Notice board is primary thing in any institution or organization or public utility places like bus stops, railway stations or parks. But sending various notices day-to-day is a tedious process. This project deals with advanced notice board. It presents an SMS based notice board incorporating the widely used GSM to facilitate the communication of displaying message on noticeboard via user's mobile phone. Its operation is based on microcontroller AT89c52 programmed in assembly language. A SIM300 GSM (Global System for Mobile communications) modem with a SIM card is interfaced to the ports of the microcontroller with the help of AT commands.
