I'm busy at the moment writing a textbook for automotive students in the Netherlands using the Arduino Uno. I like permission to use the word Arduino in the text and on the front cover. It is open source publishing. Who can I asked for advice and permission.
I have no idea, but your title gives no hint of your problem.
I suggest you edit your Original Post and change the title to something like "Permission to refer to Arduino in book I am writing"
You need to ask a member of the Arduino team, such as Massimo Banzi email@example.com
