Jargon buster

Plain-language definitions for the technical terms used above.

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.
servo
A servo is a motor with built-in position control, usually told to move to a specific angle by a control signal. It matters when you need repeatable movement, such as steering, arms, flaps, or linkages, rather than continuous spinning.
Ultrasonic module
An ultrasonic module measures distance by sending out high-frequency sound pulses and timing their echo. It is commonly used for obstacle detection and simple range-finding projects, but it needs a clear path to the target.
