Wireless / RFID / NFC

RFID / NFC technology is a great way to interact with projects. NFC (Near Field Communications) is a way for two devices very close to each other to communicate. Sort of like a very short range bluetooth that doesn't require authentication. It is an extension of RFID, so anything you can do with RFID you can do with NFC. Because it can read and write tags, you can always just use this for RFID-tag projects. For a good example of how these boards can be used, check out Becky...

PN532 NFC/RFID controller breakout board [v1.6] ID: 364 ...

Description-

The PN532 is the most popular NFC chip, and is what is embedded in pretty much every phone or device that does NFC. It can pretty much do it all, such as read and write to tags and cards, communicate with phones (say for payment processing), and 'act' like a NFC tag. If you want to do any sort of embedded NFC work, this is the chip you'll want to use!

Solder the Headers

The first step is to solder the headers to the shield. Cut the header strip to length and insert the sections (long pins down) into an Arduino. Then place the shield on top and solder each pin.

Using the Adafruit NFC Shield with I2C

The Adafruit NFC shield is designed to be used using the I2C by default. I2C only uses two pins (Analog 4 and 5 which are fixed in hardware and cannot be changed) to communicate and one pin as an 'interrupt' pin (Digital 2 - can be changed however). What is nice about I2C is that it is a 'shared' bus - unlike SPI and TTL serial - so you can put as many sensors as...

Which Library?

In the past there were two separate Arduino libraries for using the Adafruit NFC boards. �One library supported the breakout over a SPI connection, and the other library supported the breakout or shield over an I2C connection. �However both of these libraries have been merged into a single Arduino library, Adafruit-PN532 .

The Adafruit PN532 library�has the...
