3mm Green LED (Pack of 10) Original Arduino Uno reed switches can be fragile3 mm Green LED (Pack of 10) A Green light emitting diode (LED) is a semiconductor light source. LED's are used as indicator lamps in many devices and are increasingly used for other lighting. It looks like a white led and illuminate's blue light. When a light emitting diode is switched on, electrons are able to recombine with holes within the device, releasing energy in the form of photons. This effect is called electroluminescence and the colour of
