LEDs - those blinky things. A must have for power indication, pin status, opto-electronic sensors, and fun blinky displays.

Jargon buster

Plain-language definitions for the technical terms used above.

LED
A light-emitting diode (LED) is a small electronic component that emits light when current flows through it in the correct direction. Because it only conducts one way, its polarity matters, and a through-hole LED must be soldered the correct way around to light up.
