A Light Emitting Diode that emits one color when forward biased and another color when reverse biased is called a multicolor RGB LED. Related Article: Working of Light Emitting Diode (LED) One commonly used schematic symbol for these LEDs is shown below. Working of Multicolor RGB LEDs Multicolor RGB LEDs actually contain two PN junctions that are … [Read more...] about How Multicolor RGB (Red Green Yellow) LEDs Work?
A light-emitting diode (LED) is a diode that gives off visible light when forward biased. Light-emitting diodes are not made from silicon or germanium but are made by using elements like gallium, phosphorus and arsenic. By varying the quantities of these elements, it is possible to produce light of different wavelengths with colors that include red, green, yellow and … [Read more...] about Working of Light Emitting Diode (LED)
