The Boolean logic gates AND, OR and NOT comprise transistors, which are on/off switches wired together. Gates have one or two inputs but only one output, and they are wired in patterns that make ...

You guessed it, diodes can also be used to build logic gates, but not all of them ... all other gates can be implemented. The three input, diode-only AND gate is shown in the picture above.

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 ...
