No one can deny the convenience of a television remote control these days. And now they seem to be able to do most anything – from changing channels to initiating recordings. But what is the technology behind these little devices that make them magically bring up the TV guide or raise and lower your flat screen television in your TV lift cabinet?

Remote controls were first used in WWI by German naval vessels to direct them into Allied boats. Then in WWII, remote controls were used for detonating bombs. Now over sixty years later, remote controls have a much more peaceful use.

For at-home use, most remote controls are powered by infrared (IR) technology. Infrared light is also referred to as “heat,” and remote controls rely on the use of light to carry its signal from the control to the device it directs. On the electromagnetic spectrum, infrared light falls on the invisible portion, between “visible” and “microwave.”

The signal sent out by the remote control is in binary code; that’s how
