Abstract:

Notice Board is a primary thing in any institution/organization or public utility places. Sticking various notices day-to-day is a difficult process. A separate person is required to take care of this notices display.This is the model for displaying notices in colleges on electronic notice board by sending messages in form of SMS through mobile; it is a wireless transmission system which has very less errors and maintenance. The hardware board contains microcontroller ATMega328p at the heart of the system. A SIM800 GSM modem with a SIM card is interfaced to the ports of the microcontroller with the help of AT commands. When the user sends a SMS via a registered number from his mobile phone, it is received by SIM800 GSM modem at the receiver’s end. . The messaged is thus fetched into the microcontroller. It is further displayed on an electronic notice board which equipped with LCD display. This project is our experiment on real time noticing.
