WebAug 11, 2024 · Working of LED. Like an ordinary diode, the LED diode works when it is forward biased. In this case, the n-type semiconductor is heavily doped than the p-type forming the p-n junction. When it is forward biased, the potential barrier gets reduced and the electrons and holes combine at the depletion layer (or active layer), light or photons … WebA PN-junction is formed when an N-type material is fused together with a P-type material creating a semiconductor diode.

You can do this with a bi-color LED that has the two LEDs back-to-back if you connect one LED terminal to an intermediate voltage eg 2.5V on a 5V design and connect the other side to the MCU via a suitable resistor (I used 560R). Then a low output gives one colour, high gives the other and tri-state leaves the LED off. iland witch
