Getting Started with RFID 1 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. The book assumes that you have some experience with Arduino and micro-controllers (i.e., do you know what a breadboard, jumper wires, and circuits are?).

We start with a very brief introduction to RFID, follow up with two introductory technical tutorials...
