In the previous post, two parallel switches implemented an ideal OR condition: either closed branch completed the lamp circuit. In Post 2, two series switches implemented AND: both contacts had...
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. But...
TL;DR: AND, OR, and NOT are three fundamental logic gates. AND outputs 1 only when all inputs are 1; OR outputs 1 when any input is 1; NOT inverts...
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...
