My new Arduino always gives me an error

Have you read the pinned posts at the top of the forum you've posted in?

How about telling us a bit more about your setup.

What board are you having problems with. What OS are you using, etc....

I use Manjaro Linux with an Arduino Uno. I press upload and my error comes.

Did you select the correct port?
Are you as member of the dialout group?
Is your board correctly recognised? lsusb and dmesg can give insight in that.

You can enable verbose output during upload (please disable verbose output during compilation) in file -> preferences in the IDE. After the error, click the copy error messages button at the right in the orange bar and next paste here in a reply.

avrdude done. Thank you.

This report would have more information with
"Show verbose output during compilation"
option enabled in File -> Preferences.

Emphasis added :wink: Are you a member of the dialout group? If not, add yourself. After doing so you have to logout and login for the changes to take effect.

Can you tell me how to do that, please?

Thanks!

Arduino - Linux.


It is not working

From your error message, it's not /dev/ttyACM but /dev/ttyUSB0
