1. An electronic device comprising:
- a component; and
a light circuit including a light emitting diode and being structured to have a first mode to generate light with the light emitting diode and a second mode to detect light with the light emitting diode;
a function selection circuit structured to control the light circuit to operate in the first mode or the second mode; and
a light control circuit structured to drive the light circuit to generate light with the light emitting diode when operating in the first mode,wherein the light circuit is structured to output a detection signal in response to detecting light when operating in the second mode, andwherein the detection signal is used to wake up or communicate with the component.
