An infra-red LED is just like any other LED except the light it puts out falls in the infra-red rather than the visible region of the light spectrum and cannot therefore be seen by the human eye.
Infra-red LEDs are used in TV-style remote controls and their signals are received by infra-red receiver chips.
Infra-red LEDs can also be controlled by a PICAXE using the irout command and can be used to control TV and other equipment and be used to communicate between PICAXE.
An infra-red LED may be used via the IR LED module.
