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.

DC

DC means direct current, where electricity flows in one constant direction, as supplied by batteries, USB ports and many plug-pack power supplies. When a product specifies DC, it runs from a DC supply rather than mains AC, so you need to provide the correct voltage and polarity.

pH

A measure of how acidic or alkaline a liquid is, on a scale where 7 is neutral. For a water monitoring kit, pH tells you about water chemistry and whether the included probe matches the range and accuracy your project needs.

through-hole

A mounting style where the component leads pass through holes in a circuit board and are soldered on the other side. Through-hole parts are often easier to handle and solder by hand, which is useful for classroom and hobby projects.
