Detailed Description

The rotary encoder (ENC1) on D3 and D4, and its push switch on D2.

The shield has pull-ups and RC filters on all three lines, so they are inputs with no pull of their own and read low when closed. Pin interrupts count the turns, so none are missed while your program does something else.
