Well, we might be

but not all
that clever, especially when we're short on time. I'll have to check those possibilities, Eric. Where does the data wire(s) get connected? Right now I'm in the "one step back" mode (computer doesn't want to download to the Arduino), so it'll be a bit.
All I need is to send a single number to the Arduino, and it'll turn on some LEDs. Can I do it through a Digital IO (which sounds the simpliest method)? WPI_PWMSetValue.vi?
Just saw Adam's post: Yeah, it's not quite decorative LEDs, so thats out. Any of the LabVIEW I2C examples are good to look at? Or the serial?
