Electricity doesn’t just flow freely in every direction—it needs control. That control comes from a tiny but powerful ...

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 ...

Unlike filament lamps, where electrical energy must be converted into heat before light can be produced, Light Emitting Diodes (LEDs) are able to transform electrical energy directly into light energy ...
