Jargon buster
Plain-language definitions for the technical terms used above.
- AWG
- American Wire Gauge is a numbering system for wire thickness, where a lower number means a thicker wire. The AWG rating matters because thicker wire can usually carry more current with less voltage drop and heating.
- 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.
- NeoPixel
- A type of addressable LED system where colour data is sent along a single digital data line from one LED or controller to the next. Compatibility matters because the timing and signal format must match for the lights or driver board to respond correctly.
- WS2812B
- A smart RGB LED chip with a tiny built-in controller, commonly used in addressable light strips and panels. It matters because many WS2812B LEDs can be chained together and controlled from one microcontroller pin, but they need compatible code and careful power planning as the number of LEDs grows.
