Connect via USB with Arduino Duo

Development Tools Cloud Editor
1

I am setting up the Web Editor to connect with an Arduino DUO board. I have downloaded a plugin and installed it. I get an error message "unable to find board" when I try to connect with the board. I do have the yellow led turned on.
Need advice, thanks

I'm not familiar with the Arduino DUO. Do you maybe mean the Arduino Due?

I'm not familiar with this error message. Would you mind posting a screen shot? If you click the "Reply" button here, you will see an "Attachments and other settings" link that will allow you to make the attachment.

The most common reason for that error is that a part of the installation may have been missed.
The posts at the top of this forum section cover those aspects.

Other reasons can often be down to lack of permissions in one way or another.
Be those general user permissions or network permissions.

Some other factors below.
