Abstract: Sometimes it is very much essential to control the home appliances and different devices from a far distance. This paper gives an idea of developing a system which will enable user to control from a remote using a mobile phone based interface. Within the large coverage area of the service provider mobile phone is used to control the devices which may be located geographically far apart. CPLD is used here to direct the interfacing circuitry either to switch on or off the devices connected with it. CPLD based system is used due to faster implementation and hardware verification facilities. The device is programmable and reconfigurable. This is one of the most powerful advantages of using the device where the program is to be changed frequently for some specific applications. The functions associated with the assigned keys are stored in the CPLD. It processes the data coming from the output of a DTMF decoder and generates the output according to the key pressed from the mobile phone at the transmitting end. Xilinx 9.2i software is used to write the program in VHDL and the hardware is implemented with the help of VLSI trainer kit (Model: UNI-BSX-M1, Manufacturer: Milman).
