Wireless Communication between Personal Computer & Micro-Controller

When people have a good connectivity at their disposal, with tremendous power of mobile computing to supplement the same, we can think of connecting their home appliances to the personal computer or a laptop". With this, people would be able to turn on and off, and to some extent, control the appliances at their home even from a distant place. One of the very basic examples of an utility of this is switching on the air conditioner in the room just some time before reaching home, so that the room is sufficiently cool by then. The usefulness of a long range remote control to home appliances has no limits. A trivial setup facilitating such a thing would be to connect the home appliances, to a microcontroller receiver antenna that receives the controls from the user, the means of sending the transmitted signals to the appliances may be via a circuit or through a wireless media like Infra-Red or the RF, We have had Infra-Red Remote Controls, which work over very short distances, and Radio Wave Remote Controls, which work over larger distances. However, something fundamentally common with all these controls is that the transmitter and receiver should both use some kind of wireless waves. The project is an implementation to the idea of the wireless communication between a PC and a microcontroller. The project deals with displaying this possible wireless communication by transferring message from PC to the LCD through wireless media.
