[PD] Arduino, Pd and ultrasonics: HELP needed for degree project!

Collin, Pat, thanks for your replies.

Collin, I will try the route method in a short while...

Pat, that's interesting you use Messenger. I considered it but as I got SMS
working quite quickly I've since disregarded it. I will give it a go. Do you
mean to apply the identifier at the arduino stage, and if so, what does the
code look like? And how does Pd decipher it? I'm sorry, but nothing is
obvious to me at this stage - it's all new and I'm trying to make sense of
it.

Many thanks
