Build a Babel Fish Language Toy with the NFC and Wave Shields

Build a Babel Fish Language Toy with Adafruit RFID and Wave Shields for Arduino
http://learn.adafruit.com/babel-fish

Learn to make a speaking, card-reading toy! The Babel Fish helps you learn to say words and phrases on RFID flash cards by reading the card and playing an associated sound file loaded on an SD card inside. This project is very straightforward and could make a great jumping-off point for your own awesome RFID and Wave Shield project!

Free Webcast 4/29: Beginning NFC with PhoneGap and Arduino
http://www.oreilly.com/pub/e/3069

Don Coleman, Tom Igoe, and Brian Jepson (authors of Beginning NFC ) will introduce you to Near Field Communication using Android phones, Arduino, and NFC readers for computers and Arduino. Learn how information on NFC tags is stored and retrieved, how to write applications on Arduino and Android to read and write tags, and how to integrate NFC into larger projects. Two demos in this session will feature :

    Reading a tag with an Android PhoneGap application
    Writing to a tag from Arduino

And when both are done, we'll be able to show you how an Android device can read the tag you wrote from Arduino and take an action based on the data you stored.

PN532 NFC/RFID Controller Shield for Arduino + Extras - We've taken our popular Adafruit PN532 breakout board and turned it into a shield - the perfect tool for any 13.56MHz RFID or NFC application. The Adafruit NFC shield uses the PN532 chip-set (the most popular NFC chip on the market) 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!

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. You can do more stuff with NFC as well, such as communicate bi-directionally with cell phones

Because it can read and write tags, you can always just use this for RFID-tag projects. We carry a few different tags that work great with this chip. It can also work with any other NFC/RFID Type 1 thru 4 tag (and of course all the other NXP MiFare type tags)

The Adafruit shield was designed by RF engineers using the best test equipment to create a layout and antenna with 10cm (4 inch) range, the maximum range possible using the 13.56MHz technology. You can easily attach the shield behind a plastic plate with standoffs and still read cards through a (non-metal) barrier.

This shield is designed to use I2C or SPI communication protocols. I2C is the default, as it uses fewer pins: analog 4 and 5 are used for I2C (of course you can still connect other I2C devices to the bus). Digital #2 is used for "interrupt" notification. This means you don't have to sit there and 'poll' the chip to ask if a target tag has been found, the pin will pull low when a card, phone, etc is within range. You can adjust which pin is used if you need to keep digital #2 for something else. It is also easy to change the shield over to SPI where you can use any 4 digital pins by shorting two solder jumpers on the top of the PCB. Compatible with any "classic" Arduino - NG, Diecimilla, Duemilanove, UNO - as well as Mega R3 or later. For using the I2C interface with Mega R2 or earlier, two wires must be soldered as the I2C pins are in a different location on earlier Megas.

Comes with: the Adafruit NFC/RFID PN532 shield including a tuned 13.56MHz stripline antenna, 36-pin 0.1" header for attaching the shield to an Arduino. If you want to stack another shield on top or below, check out our stacking headers that allow pass-through stacking. We also toss in a Mifare Classic 1K card! (You can get more tags from us here)

Free Bird

Today I catch another bird in my house. She is very beautiful. I take several shots with her, then let her fly into the sky. So I hope the #Occupy Central, #Umbrella Revolution dream come to be true.
