Radio Frequency ID and Near Field Communication using the PN532. Overview. Breakout Wiring. Shield Wiring. intentionally waits around in a blocking delay until a card enters the magnetic field. The reason for this blocking delay is to ensure a well-understood command/response flow. Adafruit PN532 NFC/RFID Controller Shield for Arduino

Why You Shouldn't Always Use the Arduino Delay Function

/5/2012I was writing a blog post about reading in text files for Arduino as it doesn't have a file system and I found this post. Its really handy and combines stuff I had looked at. And also what is the relation between the delay set in the arduino after each LED (500) on command and the delay provided in the processing code do they

Build Your Own RFID Technology Using an Arduino MEGA

Reddit doesn't seem to be much help, so I'm posting here as well. . I'm try to read (what I think is) an HID Duoprox II 125kHz FSK RFID and am having a bit of trouble. I'm using an Arduino nano and am copying the code from the Arduino Playground. The changes I've made to the code are adjusting the frequency to 125kHz, changing debug to true, and reducing maxBuf to 100.
