The infra-red sensor decodes any correctly modulated infra-red light signal it receives and passes this to a PICAXE. This allows key presses on an infra-red remote control or infra-red commands sent from another PICAXE to be detected and acted upon.

Read an infra-red key press code
This program will receive key presses from an infra-red remote control using an infra-red receiver connected to input pin C.0 and will display all key press codes in the 'b1' variable. The infra-red remote control must be set to produce Sony TV infra-red command codes.
- Code Example:
-
main: irin C.0, b1 ; Wait for a key press code debug ; Display the value goto main ; Repeat
