void setup() { pinMode(3, INPUT_PULLUP); }This can be useful when you don’t want a pin to be floating, e.g. when you connect a button to a pin.Note that the analog pins can also be used as digital pins, using the aliases A0, A1, etc. The exception is the Arduino Nano’...

ISR between all the pins on a port (port B, C, and D). And anytime a pin changes on that port, it calls the port’s ISR which must then decide which pin caused the interrupt. So Pin Change Interrupts are harder to use but you get the benefit of being about to use any pin. ...
