Hello. Newb here. I've searched but can't confirm which pin is used if i want to use AttachInterrupt (0) on a Micro. Sample sketches i've seen say to use pin 2, but i've seen mention that Micro pins are different than, say, an Uno.
I'm hoping this is the reason my little project isn't working.
Thx. in advance.
Marty
Everything (and more) is online.

The Arduino Micro is the same as the Arduino Leonardo, only a smaller board. So you have 5 possible pins for interrupts.
Beside the 'real' interrupts like INT0, there are also pin change interrupts like PCINT0.
