I am setting up an IR receiver/transmitter (with an Arduino Uno) that turns certain AV components on and switches inputs, and now it is controlled by buttons, but I'd like it to have knowledge of the on/off state of certain hardware (apple tv and cable box) so it could turn to the correct input when…

Sensing when Apple TV or Cable Box LED comes on.
