connecting a pot to max with an arduino

Arduivis is looking more and more attractive; but I still have to admit that I'm a little in the dark as to how he gets raw 10-bit into Max over the Serial port 8-bit byte limitation. I've done it myself using bit-shifting, but this looks so damn simple and efficient. Must be something to do with ASCII conversion and [zl slice 1000].

I'd also like to learn how he parses multiple discrete sensors in this way.

Thanks for the timely reminder opkach
