mknod? this sounds like you are following advice from the 1990s. these days mknod is hardly ever needed: instead any devicefiles will be created on the fly by the resp. drivers.
selecting device in the toggles in the pduino stuff only finds device 0
I am wondering if it's a linux issue because the only serial port at all is
serial 0 /dev/ttyAMA0
a little bit of googling hints that /dev/ttyAMA0 is indeed the name for the serial interface on the GPIO ports - which afaiu is what you want.
so you just use that device.
then you need to get the permissions correct. check whether the device is already setup to allow group-members to write to it, and which group that is: $ ls -l /dev/ttyAMA0 crw-rw---- 1 root dialout 4, 67 Sep 3 16:12 /dev/ttyAMA0
and eventually add the user running Pd to that group: pd@raspbian $ sudo bash root@raspbian # adduser pd dialout
after that you only need to re-login as that user to let the new group membership have any effect.
