AND Gate from Relays: George Boole's Algebra, Wired in Copper
In the previous post, you wired two switches in parallel and felt OR emerge from the circuit itself — a lamp that lights when either switch closes. In Post 2,...

Switches in Series: The Hidden Logic of AND
In the first post in this series, we learned that a relay is a switch thrown by electricity — one circuit controlling another. That single device already hints at logic....

Digital Logic 101: Your First Steps with AND, OR, and NOT Gates
TL;DR: AND, OR, and NOT are the three fundamental logic gates. AND outputs 1 only when all inputs are 1; OR outputs 1 when any input is 1; NOT inverts...

The AND Gate: Foundation of Digital Logic and Decision Making
TL;DR: An AND gate outputs 1 only when every input is 1; otherwise the output is 0. Boolean expression . Despite the simple logic, real AND gates have non-zero propagation...
