Adafruit NFC/RFID on Raspberry Pi @Raspberry_Pi #piday #raspberrypi
Interested in adding some NFC fun and excitement to your Raspberry Pi? You’re in luck!
One of the big advantages of Linux is that it includes a large number of stacks that have been developed by the open source community, and you get to take advantage of all that hard work simply by using or installing the right library.
NFC is no exception here, with libnfc having been around for a quite some time — in fact, it’s the original reason the NFC Breakout was developed!
To get libnfc playing well with your Pi and your Adafruit NFC breakout you’ll need to make some minor modification to your vanilla Wheezy distribution, and one small change to the latest NFC code (1.7.0-rc7 as of this writing), but it’s pretty painless, and this tutorial will show you everything you need to do to start writing your own NFC-enabled apps on the Pi!
PN532 NFC/RFID controller breakout board – v1.3 – 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. (read more)
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
