GSM based device switching using ARM7 TDMI LPC2148 PROJECT TITLE : GSM based device switching using ARM7 TDMI LPC2148 ABSTRACT : In this paper, we have developed a high security, simple and reliable wireless Communication system to monitor and to control devices that are far away from the user by making a call. The mobile which is connected to the system is kept in ‘auto answer’ mode. Using DTMF technology, any devices can be switched and controlled by pressing the corresponding buttons during the course of a call. These tones are then decoded by using a DTMF decoder and the corresponding devices are chosen. Did you like this research project? To get this research project Guidelines, Training and Code...
