Raspberry Pi Sensors

Raspberry pi sensors is a great source for those who want to learn or teach how to use sensors. The author gradually introduces the reader to electronics. Each chapter include the concepts necessary to understand not just how to wire/program the sensor but also explain how it works. Chapter 5 describes how to add an ADC (Analog to Digital) interface to the Raspberry Pi. Regardless if the reader decides not to build any of the other projects listed in the book, ADC project in chapter 5 is a most. ADC support expands your Raspberry PI device interface capabilities. There is one area partially addressed by the author. There are multiple references to I2C interface but no example how to communicate with I2C sensor and gather data sample

This book is just a waste of money. I followed instructions in this book to play with my RaspberryPi, but many of them didn't work. Then, I had to Google it, then, following many online instructions (some of which worked while the others didn't). I bought this book with a hope that I could save time from Googling instructions for what I wanted to do with my Pi. However, it turned out that the book wasn't worth it. I want my money back if I could!
