Circuit Diagram

This provides a visual reference for wiring of the components. They aren't true to scale, just meant to be used as reference. Generic micro switches follow a standard pin out with visible markings on the body of the switch. Here's each label markings:

(C1) – "common ground".
(NO2) – "normally open".
(NC3) – "normally closed".

Wired Connections

Just two wired connections are needed for this circuit, which makes it very easy!

(C 1) Common from micro switch to Ground on Trinket M0
NO 2) Normally open from micro switch to #0 on on Trinket M0
