[PD] Pduino and arudino mini pro/raspi debian- Pduino or Comport?

[Ivica Ico Bukvic]

If connecting to serial port works when you run pd with sudo privileges, 
you will need to add your user is to the dialout group. See 
http://unix.stackexchange.com/questions/14354/read-write-to-a-serial-port-without-root 
for more info. HTH
