There are several places which require vital notice to be displayed like colleges, railway stations, share-market, restaurants, hospitals etc. Looking into the present trend of information transfer it is seen that vital notice take time to be displayed on the displaying boards. This latency is not anticipated in most of the cases and must be avoided. The advancement in the technologies related to wireless communication has led to the emergence of several engineering designs to aid the human requirements. This paper presents a combination of wireless technology with LED Display Boards formalized by designing and integrating the hardware and software with AT89S52 microcontroller, GSM module, LCD, moving LED display. The proposed design overcome the difficulties faced by previous moving text message display modules using wired entry via computer, keyboard or remote control entry (small distance). The message is sent through a cell-phone which is accepted by the GSM module SIM 300 (master). Number authentication is done by AT89S52 microcontroller and the stored numbers in EEPROM is compared with the incoming number. The message will be valid only after the incoming cell phone number is validated. Authentication result is displayed on LCD whether the number is matched or not matched and the message is finally displayed on moving LED (Light emitting diode) display. Further the same SMS is itself sent by GSM module (master) to Multiple LED Display Boards which are connected via different GSM modules (slaves). The incoming number and the message are stored in EEPROM so that no previous message is lost even after power failure.
