Jargon buster
Plain-language definitions for the technical terms used above.
- DC barrel jack
- A round power connector commonly used for low-voltage DC power supplies, often described by its outer and inner diameters such as 5.5 x 2.1 mm. Matching the barrel size and polarity is important so the plug physically fits and powers the device correctly.
- 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.
- Terminal block
- A connector used to join wires together in a neat, removable, or serviceable way. For this product, it helps split one power input into several outputs without soldering.
