WIRELESS NOTICE BOARD BASED ON ARDUINO AND GSM TECHNOLOGY

This paper deals with an interesting and innovative manner of displaying messages on an electronic display board using wireless technology. Notice boards are one of the basic things in any organisation or public utility places likes hospitals, airports, bus stations, railway stations, shopping malls and parks. It is time consuming and tedious process to manually write down the different notices every now and then. To overcome the problem, the idea of wireless digital display board has been proposed in this paper. The key objective of this project is to develop a notice board that receives and displays messages from an authentic user from anywhere in the world using GSM technology. The SIM card loaded in the GSM module fitted with the wireless display board receives messages from authorized user having a mobile phone. The received message is then displayed on the wireless notice board making the whole process easy and fast. Thus the authentic users can send messages from any corner of the world to be displayed on the notice board using GSM technology.
