“GSM based Control System” 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 appliances and other devices locally using built-in input and output peripherals. We propose to make the system which is designed to display the message received by the cell or a modem. Then microcontroller will control the system by using the programming commands and the messages will be displayed on the LCD.
