It is a Led blinking program. A light-emitting diode (LED) is a two-lead semiconductor light source. It is a basic pn-junction diode,
which emits light when activated.[7] When a fitting voltage is applied to the leads, electrons are able to recombine with
electron holes within the device, releasing energy in the form of photons. This effect is called electroluminescence, and
