Topic: pin number. (Read 1 time) previous topic - next topic


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:

Code: [Select]

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.


Thanks! so, the numbers that i see in the board are the numbers used in the programming?

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().
