We (6people) met today to play around with arduino and do the tutorials. We have two different productions of arduino cards.
our scool (HfG Schwäbisch Gmünd) bought 10 Pieces and i by myself bought 10 as well.
We did the Knightrider Tutorial.
3 people, working with the cards (number 1963, 1960, 1964) from scool, don't have problems The other three are working with the cards i bought (number 1405, 1403, 1398). The lowest pin (2) is not working and we don't understand why If we declare Pin 3 as lowest Pin, Pin 3 is not working?!
What can it be? Is it the firmware of the Chip on the board? Is it possible to update it?
