Microcontroller Design for Publicity Control

Abstract

This research displays the design of remote control system based on Short Message Service (SMS) for displaying publicity on Liquid Crystal Display (LCD’s). By sending messages in the form of SMS through mobile; It is a wireless transmission system which has very less errors and maintenance. The control center is supplied with Global System for Mobile communications (GSM) for SMS transmission and reception. The GSM receiver is connected to a microcontroller (AT mega 32) the heart of the system,(is used to store the timings and messages to be displayed, decodes the messages and accordingly sends commands). The microcontroller issues orders to display advertisements as required by the message. It's interfaced with LCD (40*2) display unit. Microcontroller coding will be done using Embedded PASSCOM. The control system consist of two separate units, control center and control unit. In the control center a PC can be used with an administrator for monitoring the system so can operation indoors, the indoors electronic devices are within the temperature and humidity limits for proper operation of the hardware where as the control unit operates outdoors. The outdoor units must be fully enclosed and protected from the climate changes for the safety of the hardware
