Logic Sequencer
Scrap Mechanist built a sequencer to take 3 switch inputs and always output in order 1,2,3 regardless of the input order.
Here is a 3x4x1 version of a sequencer. Light to dark blue are inputs 1-3.
Light to dark red are outputs 1-3.
Any 1 blue activated = output 1 on
Any 2 blue activated = output 2 on
Any 3 blue activated = output 3 on
