7.10 The IR Receiver
Infrared communication is a common, inexpensive and easy-to-use wireless communication technology. IR light
is very similar to visible light, except that it has a slightly longer wavelength. This means that IR is
undetectable to the human eye – perfect for wireless communication. Example: When you hit a button on your
TV remote, an IR LED repeatedly turns on and off, 38000 times a second, to transmit information to an IR
photo sensor on your TV.
