CODE | IR Remote Control Light - Arduino Project 050
An IR remote and receiver communicate with each other by transmitting and decoding a signal in the form of pulsed IR radiation.

Infrared radiation (IR), or infrared light, is a type of electromagnetic radiation with wavelengths ranging from 700 nm to 1 mm. Because humans can only see light with wavelengths of roughly 400 (violet) to 700 (red) nanometers, IR radiation is invisible to the human eye.
