For this, a bistable multivibrator was used, or as it’s called in the world of digital logic and Minecraft circuits, an S-R flip-flop. This flip-flop needs two inputs; one to store the value and ...

The logic only uses NAND gates, but if you consider the flip flop outputs as A, B, and C, it is easier to think of the logic as (A&B)|(B&C)|(A&C). If you apply DeMorgan’s theorem you can convert ...
