The first edition of this book was published in November 2011 and has been Amazon’s highest ranking book on Arduino.
At the time the book was originally written, the current Arduino model was the Arduino 2009 and the software version was Beta018. Almost at the time the book arrived in stores, the Arduino Uno and version 1.0 of the Arduino software were released. Soon after, the second printing of the book had a minor update to cover the new board and software without formally being a second edition. This edition brings the book fully up to date and is based on Arduino 1.6.
The Arduino Uno R3 is still considered to be the standard Arduino board. However, many other boards, including both official Arduino boards (like the Leonardo, Zero, 101, Due, and Yun) and other Arduino programming language–based devices like the Photon and Intel Edison, have also appeared.
This edition also addresses the use of Arduino in IoT (Internet of Things) projects and the use of various types of display including OLED and LCD.
