Remote controllers aka remote commanders are very simple devices that contain only a few components. If you ever "dissect" a typical remote controller you will see only a few components. These would include a circuit board, an integrated chip, a transistor, a capacitor and one or two resistors plus the usual battery contact points and Light Emitting Diode (usually Infrared).
"So the basic operation of the remote goes like this: You press a button. When you do that you complete a specific connection. The chip senses that connection and knows what button you pressed. It produces a morse-code-line signal specific to that button. The transistors amplify the signal and send them to the LED, which translates the signal into infrared light. The sensor in the TV can see the infrared light and "seeing" the signal reacts appropriately." (From Howstuffworks.com )
The other day I was at a friend’s place and he was showing off his new Bose sound system. To my astonishment he changed songs on the CD system using a remote controller (we were sitting on the roof, 2 floors above his room where the system was placed!!!). You can very well guess that it was my first experience with a RF (radio frequency) remote controller. Its your basic remote controller with a slight difference, it uses radio frequencies instead of infrared light signals. The infrared remote control has to be in direct line of sight of the receiving senor (in the TV, VCR etc) while the RF remote can be anywhere and still function perfectly. So you can practically be anywhere in your house and still use your remote controller.
