Oh really?
Let's keep in touch over email. I think we might find ourselves picking eachother's brains...
I think bluetooth is too limited a range (10m for class 1, 100m for class 2, but there's very few class 2 devices out there)
xBees are something like 400m for the pro version, and 100m for the regular. Cut that in quarter (because theatre has SO MUCH interferance from the dirty power in the lighting grid), and the Xbee pro is what I think i'm going to use.
Here's my biggest hangup. The Arduino only has 8 analog ins... Do I use 2 arduinos? Or do I just find another similar device? Is there any way of getting more inputs out of the unit? (before I go ordering them this week...)
