RFID, Unity, Arduino

hello,

i'm working on schoolproject musea exhibition.
at moment i'm controlling 3d model in unity 2 poteniameters rotate , exploded 3d model.

now have added rfid sensor scanning materials (rfid tags).

with current script in unity (and firmatestandard on arduino) don't rfid working.
when using 2nd arduino rfid separate arduino sketch , unity script worked well, need space 2 arduino's.

the current unity script potentiameters standardfirmata on arduino.

my question how last rfid script working in de first unity script uniduino. or better how data rfid in first script.

i've posted topic on uniduino , unity forums els more support in smaller time.

thanks time, greets.

quote

and firmatestandard on arduino)

that problem firmate firmate does, not rfid.
if want arduino rfid have program arduino , not turn arduino dumb i/o port, firmate does.
