Acknowledgments

More thanks than I can express go to Ann, Amelia, and Thomas. Their patience during this project has been amazing. Many thanks go to Hugh Blemings, my partner in crime, whose patient discussions during many late-night phone calls helped me understand far more about Arduino.

Thanks also go out to the technical reviewers who provided us the benefit of their expertise and years of experience: Andy Gelme, Marc Alexander, Nathan Seidle, Trent Lloyd, Scott Penrose, Thomas Sprinkmeier, and Philip Lindsay.

Of course, thanks go to the core Arduino team whose vision conjured the whole Arduino ecosystem into existence: Massimo Banzi, David Cuartielles, Tom Igoe, Gianluca Martino, David Mellis, and Nicholas Zambetti.

More than 5,000 organizations count on O’Reilly

O’Reilly covers everything we've got, with content to help us build a world-class technology community, upgrade the capabilities and competencies of our teams, and improve overall team performance as well as their engagement.

Julian F.

Head of Cybersecurity

I wanted to learn C and C++, but it didn't click for me until I picked up an O'Reilly book. When I went on the O’Reilly platform, I was astonished to find all the books there, plus live events and sandboxes so you could play around with the technology.

Addison B.

Field Engineer

I’ve been on the O’Reilly platform for more than eight years. I use a couple of learning platforms, but I'm on O'Reilly more than anybody else. When you're there, you start learning. I'm never disappointed.

Amir M.

Data Platform Tech Lead

I'm always learning. So when I got on to O'Reilly, I was like a kid in a candy store. There are playlists. There are answers. There's on-demand training. It's worth its weight in gold, in terms of what it allows me to do.
