In this book, the idea of GSM based display using Arduino Technology has been presented. We have tried to implement our system in such a way that, the GSM module which is located at Digital notice board receives the message from authorized user and displays on notice board which is situated at remote location and at the same time this message is also sent to different user¿s mobile numbers that are stored in the microcontroller memory. So circulation of important messages or notice takes place within very short span of time to respective mobile numbers. GSM-based campus display system can also be used at other public places like schools, hospitals, railway stations etc., The project has a GSM receiver and a display toolkit which can be programmed from an authorized mobile phone. The Wireless Communication Based Notice Board Using Graphical LCD receives the SMS, and displays the desired information after necessary code conversion. Being wireless, the GSM based is easy to expand and allows the user to add more display units at any time and at any location in the campus depending on the requirement of any institute.
