The light-emitting diode (LED) is a semiconductor device that converts
electricity into light.
A semiconductor diode is a two-terminal device, sometimes described as a pn.
An LED is fabricated from a semiconductor material. One side of the
semiconductor is attached to the P side which is the anode; the other side
of the semiconductor is attached to the N side, the cathode. Electricity can
flow from the p side to the n side. However, no electricity can flow in
reverse. In effect, therefore, a dio
