Raspberry Pi to Arduino Shields Connection Bridge

The idea behind the Raspberry Pi to Arduino shields connection bridge is to allow to use any of the shields, boards and modules designed for Arduino in Raspberry Pi. It includes also the possibility of connecting digital and analog sensors, using the same pinout of Arduino but with the power and capabilities of Raspberry.

The Raspberry Pi to Arduino Shields Connection Bridge is compatible with...

Arduino Library | Adafruit PN532 RFID/NFC Breakout and ...

by lady ada

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...
