LEDs form an inevitable part in the modern electronics as simple indicators to optical communication devices. Light Emitting Diodes exploit the property of the p-n junction to emit photons when it is ...

Diodes are one of the most important parts of any electronics project, and if you don't understand how they work you'll destroy any electronics project you work on. Thankfully, Adafruit has a video ...

How does a varactor diode work? To form the PN junction that makes a diode, half the piece is doped with a trace amount of “donor atoms” that have one more electron than the intrinsic stuff to make ...
