@Shinji0912 said in Is it possible to ad an Arduino?:
portname: "/dev/ttyUSB0",I think that is the wrong device name for the serial port on the pi. if you are using the gpio header pins
Ich denke, das ist der falsche Gerätename für die serielle Schnittstelle auf dem Pi. wenn Sie die GPIO-Header-Pins verwenden

@sdetweil Im not using the Gpio header pins i have the Arduino connected to the Pi using usb?
-
@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 dols /dev | grep -i usb -

@Shinji0912 don’t see ttyUSB0
are there any message on the console where u start mm? npm start? or pm2 logs --lines=?????? is a number, default is 15

@sdetweil Not as far as i can see.

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