Jargon buster

Plain-language definitions for the technical terms used above.

LED

A light-emitting diode is a small electronic component that lights up when current flows through it in the correct direction. In this kit, LEDs create the flashing effect, so polarity and correct soldering matter for the project to work.

line-tracking sensor

A line-tracking sensor detects contrast between a dark line and a lighter surface, usually using infrared light. It matters for robot activities where the robot follows a track, such as classroom challenges or competitions.

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.
