Abstract: The mobile phone technology like Dual Tone Multi Frequency (DTMF) and Global System for Mobile communication (GSM) have pushed us to control the things around us with mobile phones and the world is going mobile. Whatever appliances we are dealing with, in our daily life, we want to control them without physically moving to the control unit. As we see in our schools and colleges, we are using manual notice boards that require enough time and man power to change the notices every time we wish to change.
