Fixing Setting Up Arduino Uno IDE error on Ubuntu

Ubuntu is pretty awesome and I am loving it. I just want to burn a code to my Arduino Uno. When uploading the code, there’s an error message saying, Serial Port COM1 not fount found. Did you select the correct one from tools -> serial port menu?. Now, visiting the tools, I can’t select serial port because it is disabled. I am attaching a screen-shot of how it looks. I have done something similar in windows. How to find the serial port on Ubuntu?

Answer

COM1 is a Windows(TM) designation – it will look like /dev/ttyACM0, /dev/ttyUSB0 or similar in Linux.

Greyed out port tends to mean you haven’t set the board type first – go through the settings in arduino Tools menu & set board to ‘Uno’, you should see the ‘port’ enable & auto-fill as well, most likely.

— OR —

In case you’re using version 1.X of arduino IDE, I assume that you installed the one in the apt repositories.You can either try to install one from the snapcraft or the one from arduino’s website.

Also either the case you can try to loon on Tools->Port if exists a port that is not a /dev/ttyS0 one. Try to play with these options. Finally by searching on dmesg you can find out which port has been located for arduno as well.

Finally an another approach is to unplug your arduino plug it again and type the following command:

dmesg | tail

In order to record the last event as the one that happens when arduino is plugged in to a usb port. The command above will show you the correct port.

For better results you can try this

  dmesg | tail -f

And continioulsy plug and unplug the arduino from the usp port till you see any arduino related message. The -f parameter allows to show realtime the new logs.
