[PD] Arduino/SRF05

[Dafydd Hughes]

Hi David

I'm sure it's easier than I'm making it.

Really, I just need to turn the data from the arduino into usable
floats. Right now it's coming in as ascii characters and I'm building
lists between carriage returns. Hopefully I can now turn those lists
into numbers without too much trouble. Should I maybe be doing this
with binary numbers? Would that be easier?

cheers
