THIS BOOK wouldn’t have been possible without my coauthor, Andreas, whom I have seen grow into an excellent programmer, capable of doing almost anything related to code. Thanks as well to Sergio Villalobos from LG’s marketing department in Mexico, who gave us access to a real smartwatch while it was still impossible to get one in Sweden. To the unknown engineer at LG who kindly gave his watch to Sergio to give to us. To Troed Sångberg at Sony in Sweden who got us a Sony SmartWatch 3 to test the final chapters in the book. To Pontus Stalin at inUse for some other tools that also came in handy. To my whole team at Arduino Verkstad, who gave me emotional support just by being there’especially Mr. Duffy, who took some of the pictures for the book. Finally, to Laura, who made everything possible by helping in the day-to-day while I was writing.

THANKS FIRST TO MY COAUTHOR, friend, mentor, and former teacher for dragging me into this exciting world of tech! Who knows what I would have been doing today if I hadn’t been introduced to The Lab at K3?
Also, a big thank you to the staff at Wiley for their support and vigilant efforts in producing this book. Thanks to Chris Haviland for her help and extreme patience with me and David since the beginning of this project. Also, I’d like to thank Bob Elliott for giving us the opportunity to work on one more book together; it’s been an adventure, just like the first time. Erik Hellman and Jonas Bengtsson deserve a big thanks for helping us nail the technical side of the book.
A huge thank-you to Sergio Villalobos at LG for lending us a Wear device when none was available in Sweden. It definitely made this book much easier to write. Also, Troed Sångberg at Sony played a major part in finishing this book when he lent us a SmartWatch 3 to work on the newly released GPS libraries. Without these devices it would have been impossible to complete the book.
Finally, I’d like to extend my gratitude to friends and family for their patience during this time, and to Tony and Fernando for their support and fun conversations around all of our projects. Finally, I’d like to thank Katya for being an inspiration to me and for making me want to work twice as hard.
