Is it possible to ad an Arduino?

[sdetweil]

@Shinji0912 i have never seen arduino connected via USB… none of my arduino devices have USB plugs

did u check the available device names on your pi?
from a terminal window do

ls /dev | grep -i usb

@Shinji0912 so, I would use the linked examples outside mm to make sure it works
