[fpc-pascal] Arduino project

[tsiegel at softcon.com]

Raspberry pie just runs a version of linux, so FPC should work just fine 
on any raspberry pie.  They certainly can be run from a powerbank, I've 
done it with one of mine multiple times.  I haven't found a way to 
determine how long the powerbank is going to last, so you'll need to 
figure out how to do that, or just be prepared for everything to stop 
when the power runs out.

As for talking to the arduino from linux (the raspberry pie), I haven't 
tried that myself, but I don't expect it to be any different from when 
using windows for the host os.

Unfortunately, I don't know what resources for programming arduino 
boards exist for linux, but it can't be too terribly different from 
windows, but I've not specifically looked for linux versions of the 
various serial and/or other communications libraries you'd need to talk 
to the arduino, but as long as you can port or locate versions for 
linux, you shouldn't have any trouble with it.

Now you're making me want to experiment.  I never had a need to talk to 
an arduino from linux, even though I use it regularly, I normally build 
projects to talk to windows, because that's what most folks I'm building 
things for use.  This might be a fun project all by itself.
