Here’s a really fascinating circuit that implements a combination lock using relays and logic gates. Even with the schematic and written explanation of how it works we’re still left somewhat ...

Also known as "combinatorial logic," it ... made of primitive logic gates (AND, OR, NOT, etc.) in which all outputs of the function are directly related to the current combination of values ...

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 ...
