Module description: LED is the abbreviation of light-emitting diode. It is usually made of
gallium arsenide, gallium phosphide semiconductor material. LED has two electrodes, one
positive and one negative. When the positive current passes through, it will light up. It can
be red, blue, green or yellow light, and the color of the light depends on the material it uses.
