a brief word about infrared
Infrared is a light ray that is below the visible
spectrum, just like the sound spectrum extends
beyond your hearing ability. An example of infrared
transmission is the remote control for your TV set.
When a button is pressed, a beam of infrared light
is emitted by a Light Emitting Diode (LED) from the
IR transmission
remote control. It is detected by a receiving diode
in your TV set. When you press a certain command
