To Bobbie for being the only person I know of

learning electronics before learning how to read (and

for being so extremely patient with her dad).

To Andreas Göransson, co-author and friend because

he always exceeds my expectations. I did what I did

just because you did what you did.

ACKNOWLEDGMENTS

THANKS TO FAMILY, friends and colleagues for their support while writing this book; above all a

thanks to my co-author David for always pushing me to the next level. Also I’d like to thank Tony

Olsson and Fernando Barrajon for their support when writing this book. Special thanks go to

Richard Hyndman of Google UK for giving us the opportunity to test the original Google ADK

boards when all we had were the “knockoffs,” and a big thanks to Mario Böhmer too for sending

us photographs of the ADK boards (which we ended up not needing thanks to Richard). Also a

big thanks to Eui-Suk Chung and Seowan Kwon of Samsung for so gracefully lending us the latest

versions of their Galaxy line phones to build our projects with — and of course Hampus Jacobsson

for introducing us to them.

I would also like to extend my gratitude to everyone at Wiley for working so hard. Thanks also to

our editors, Ed Connor and Robert Elliot, in particular, for showing such great patience with this,

our fi rst, book. I would also like to acknowledge the open source project Fritzing which we used

a lot in our writing process. Finally, I’d like to thank Rodrigo Calvo for his assistance in fi xing the

USB Host libraries to work with the latest Android versions.

—Andreas Göransson

I HAVE TO THANK the whole of the Arduino family: the team, the developers, the members of the

forum, all of you that helped us making this project possible. I should also acknowledge the people

at Offi cine Arduino Torino that assisted us with getting materials for the book: Katia, Federico and

Cristian jumped in the minute we needed their help.

To Gianluca and Daniela from SmartProjects who fed our pages with boards and sensors. Rodrigo

brought to the table the brilliant idea that could patch our library in one line. Hampus introduced

us to really nice people at Samsung — Eui-Suk Chung and Seowan Kwon — who kindly lent us the

phones that made our experiments possible.

To Twitter, that let us go verbal and get people back to us. One of those was Richard, from Google,

who shipped us a Google ADK and Google ADK2. To Mario and his digital camera, it was great

to meet up in Berlin! Speaking of Berlin, the open source software Fritzing, the one we used for our

schematics, is made there.

To Tony, who made two books before we even thought about making one. You clearly showed us

this was possible. And to Malmö University in Sweden, the place where we meet and work every

day, the place that makes us think the way we think and brings us opportunities like the one of

writing this book (after normal working hours).
