LED it is a light-emitting diode, which in its structure has an anode and a cathode: the first represents the negative part, while the second indicates the positive part. They are formed by a very thin layer, which has the characteristics of a doped semiconductor, i.e. a slightly modified material. LEDs can be solid or intermittent. Thus, they either emit a steady light, never flashing, or on the contrary they blink, fast or slow.
