It’s not easy to immediately put what you learned into action (you might understand a subject theoretically but might not be comfortable enough with the subject to put it into practice).Disclaimer: I received this book for free through the O’Reilly Blogger program. is a very short “book” on RFID (Radio Frequency Identification), a way to tag and identify objects over varying ranges, and how to use Arduino to create a few interesting RFID projects.What devices are turned on at any given time depends largely on which of us is here, and what we’re doing.This project is a system to reduce our power consumption, particularly when we’re not there.Don’t be a thief—save your grade, use Bib Me™ and give credit to those who deserve it!
When either of us comes into the room, all we have to do is tap our key fobs on a reader mounted by the door, and the room turns on or off what we normally use. The reader by the door reads the presence or absence of the tags.
The book is only 28 pages, so it’s more of a long tutorial than a book, but it still acts as a good introduction to RFID.
