How well do you know your logic gates? For their final submission for STEM Projects class, [BKriet] gamified the situation using a Raspberry Pi Pico, some blinkenlights, and a not-insignificant ...

Logic gates have one or two 0 or 1 inputs but only one 0 or 1 output as in the following examples. Transistors make up gates, gates make up circuits, and circuits make up electronic systems.

In binary math, bits have only two possible values: 0 (off, false) and 1 (on, true). Consequently, there are three basic logic gates from which all other combinatorial logic functions are generated.

Some of the functions, like NOT, OR, and AND are fairly straightforward ... this teaching tool allows different logic gates to be wired together with patch cables. While [David] first thought ...

An AND gate usually has two inputs. AND tells us that both Input A AND Input B have to be 1 (or ON) in order for the output to be 1. Otherwise the output is 0.
