The book Eric Hagan and I have been working on for a while was published by Make. The book is in some brick and mortar stores, here is a link on Maker Shed.
Our book is for beginners, we wrote it for people with no background in electronics or in programming. It has lots of images. A shout out to our editor and publisher, Roger Stewart, and the production team from Happenstance Type-O-Rama, Liz Welch and Maureen Forys.
A few illustrations from the book and the cover. A lot of the content is also on arduinotogo.com, our site
