I thought this book would just cover interface circuits. What I got instead was a far more complete, detailed manual about many important features of both the Arduino and Pi. For my "Geocaching" hobby, we use Arduino to build self-contained "Geocaches" in the San Francisco Bay Area, so I am familiar with some of the input circuits of that device, such as keyboards, LED's, etc. It was fun to see all the different sensors that can be used. Great ideas to try-out!
The book divides the sensors into the following categories:
Each section has a good general overview of what you are trying to measure, and the math involved. Then, a sample sensor is introduced, with detailed instructions on how to hook it up. Tips on where to find the datasheets, along with URL's are included.
The sections on setting up Arduino and the one on Raspberry Pi are outstanding. Detailed, clear instructions on how to hook-up, download software, and get your first "Hello World" program off the ground. Includes links to websites that have the free OS or utilities.
I appreciate the information about all the extra cables, etc., that are required to get either device up and running. The low cost can be deceiving, since all the interface circuitry and cables can really add-up.
√ VERY IMPRESSIVE BOOK. HIGHLY RECOMMEND!
(I see that the publisher's HQ is not too far away; we'll have to place some Arduino-based geocachers right next to MakerMedia HQ.)
