How the Infrared Port Works
Infrared light is invisible to humans. IR wavelength is from 0.7 to 1000 microns. Household remotes use an IR signal for data transmission and operate in the wavelength range of 0.75..1.4 microns. A microcontroller in the remote makes an infrared LED blink with a specific frequency, turning the digital signal into an IR signal.
To receive IR signals a photoreceiver is used. It converts IR light into voltage pulses, which are already digital signals. Usually, there is a dark light filter inside the receiver, which lets only the desired wavelength through and cuts out noise.
