A single digital signal has only two states - on or off. However, if you use two inputs you can double the number of possible states, to four.

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.

For those just getting their start in digital logic, this teaching tool allows different logic gates to be wired together with patch cables. While [David] first thought to use 74-series logic ...

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.

A chip that contains one logic gate or a small number of logic gates. Although thousands of gates are routinely placed on a single chip, discrete logic chips with only one or two gates are also ...

The underlying circuits are a complex, networked system of logic gates that generate binary input and output signals ...

Last week, MIT researchers published a blog post highlighting a paper detailing work on fully 3D printable electronics — ...
