Use this contact form if you have business inquiries about becoming a seller for the book, using it in schools, etc. You may also use this form to report errata or website problems.
This contact form is NOT for requesting technical help with content from Exploring Arduino; requests of this nature will be ignored. I receive many requests of this nature, and it is not feasible for me to answer everybody individually. If you need help with a topic from the book, please visit the forums and other links on the resources page.
