Arduino Micro Pin # to Software Label

Analog names are A0-A11 and used as pinMode(INPUT);, int = analogRead(A3);.

DO NOT use pinMode() on pins used only for analogRead(). Use pinMode() ONLY on pins used for digitalRead() and digitalWrite(). For example, setting pinMode(A7, INPUT) on an Arduino Nano will set Pin 9 by accident.
