Hi,
I just built the Arduino Protoshield kit. I received Rev 2 of the board.
I noticed that the generial I/O button is no longer wired like the schematic -
i.e. Gnd->S2->JC1->R4->Vcc.
Instead it is now wired: Gnd->S2->R4->JC1.
Is there a reason for this change?
Just want to know if it’s ok to wire up the old way.
Also note that the analog pins are labeled backwards from that of the Arduino on this new revision.
