Adafruit PN532 RFID/NFC Controller

Last weekend we put together an Adafruit PN532 RFID/NFC Controller.  This little device can add RFID tags to any microcontroller project!  As with any Adafruit project, it was super easy to put together and their instructions for making it work were top notch.  We connected ours to an Arduino and uploaded the example sketch.

Normally to establish proof of concept, makers like to turn a light on and off or something like that.  We decided to make it a little trickier and play some music when a card is read.

We found a sketch on Pastebin with the Star Wars Imperial March song.  Somebody took the time to record all the frequencies needed to play that song, and we are grateful to them!

Here is a quick video showing the PN532 in action!
