so I was wondering if I could run the processing program simultaneously with the arduino?
Is it possible to run two arduino programs at once, though?
Or any other way to play chords?
Yup just a regular piezo. And what kind of multitasking techniques are you referring to?
such as those showcased in the Blink with Delay example.
So if I have one program that outputs to pin 8, and one that outputs to pin 9, they can't run together?
I don't know what I'm doing...
