hello i am trying to modify a code in arduino .... i want to be able read analog pins (that is ok) and to write on digital pin (this where i need help) ... everything has to run through max msp
if somebody is patient maybe he could describe a bit why it does not work
here is what i modified... (oh yeah ... i am new to all this)
