hello, i am trying to understand a code example, but i dont know the correspondence between the number and the physical pin in the arduino decimilla:

int onModulePin = 2;

I understand the rest of the code. Does anybody known what is this pin or an URL with the correspondence?

Thanks. Regards

pin number 2 will correspond to the upper pin number 3 from the right.

Yes.

Do note that the "Analog 0" to "Analog 5" can also be used as regular digital I/O pins 14-19. I think the only function requiring the analog pin numbering scheme is analogRead().
