Jargon buster
Plain-language definitions for the technical terms used above.
- GPIO
- General-purpose input/output pins are microcontroller pins you can set in software to read signals, switch devices on and off, or connect to peripherals. The number of GPIO pins matters because it limits how many buttons, LEDs, sensors, and other parts you can wire directly to the board.
- RGB
- Short for red, green and blue, the three primary colours of light that are mixed in varying amounts to make a wide range of colours. In electronics RGB can refer to an LED or pixel that blends these three colours, or to a colour signal or interface that carries separate red, green and blue channels.
- 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.
