Embedded guest information system is a very advanced technique used to inform us the arrival of a guest though we are not at home. Today in the busy life it is really impossible for us to wait at home expecting that some one may come. So hear is the new technique .The system consists of a calling bell that is connected to the telephone of that place (probably home). The heart of the project and implimentation is a micro controller. When the guest presses the calling bell of the house, the micro controller sends a binary data to the DTMF encoder, rings the telephone to the particular number stored in the micro controller. Then the person in front of the door, can speak with that number, where the host is, through the microphone /loudspeaker system attached to it. Also the person can change the number to which the guest should call whenever required from any place.
