PROBLEM STATEMENTS

      Nowadays LED message scrolling displays are becoming very popular for advertisements. These displays are used in shopping malls, theaters, public transportation, traffic signs, and highways signs. The big problem with these displays is to carry a computer or special keyboard for generating and sending messages to LED moving display boards dynamically. Carrying a host computer or special keyboard every time to generate message for LED display boards is big headache and also increase cost and waste their time .So for this project it is using a GSM.This project implements the emerging applications of the GSM technology. Using GSM networks, a control system has been proposed that will act as an embedded system which can monitor and control the other devices locally using built-in input and output peripherals. This system allows the user to effectively monitor and control the advertisement board via the mobile phone set by sending commands in the form of SMS. The type of the message to be performed depends on the nature of the SMS sent.
