Just in case this is useful...

I'm using a billion sensors in my project and realized a small problem: the Arduino only has 6 analog in pins (unless you use the Nano which has 8). So can how can you get the Arduino to 'feel' more sensors? With a multiplexer! And I found a tutorial from Igoe at ITP for it here: http://itp.nyu.edu/physcomp/Tutorials/Multiplexer

Just a little knowledge to add to your P.Comp. bank...

Nice! Thanks. I posted a trick to treat digital data like analog data too.
