Tutorial's license

[levicivita]

Do the introductory tutorials (these ones https://www.arduino.cc/en/Tutorial/BuiltInExamples) have any kind of license or copyright?
I know the code itself is public domain, but what about the explanations around it, the circuit and the schematic? Are those also completely free?

Thanks

If you scroll all the way to the bottom of the page, you will see "© 2018 Arduino".

So I guess you'd need to ask their permission.
