Arduino Playground - ParallaxRFIDreadwritemodule

Code for using the Arduino with the Parallax RFID reader/writer

This page is specifically for help with interfacing the Arduino with the newer, black read/write RFID modules from Parallax. If you need help with the blue, read-only module, please visit its page .

To learn more about the module itself, click here .

For the sample code below, the wiring should be set up as:

VCC -> +5V (Arduino)

Arduino Playground - ID12

Code for the Innovations ID-12 RFID tag reader

This is a piece of code that lets you read out the ID-12 RFID tag reader (sparkfun.com) with an Arduino. The reader uses a 9600 baud serial connection with the Arduino. When uploading the sketch, you need to pull out the RX wire to the reader, otherwise it will disturb the uploading. (Alternatively, alter the sketch, use NewSoftSerial, and also...

Arduino Playground - LiquidCrystal Library

Breadboard Sketch: LCD_using_74HC595_and_SPI.png

and replace the LiquidCrystal folder in the libraries folder of your Arduino installation directory with this one.

You can see an example sketch from "File -> Examples -> LiquidCrystal -> HelloWorld_SPI".

To create a new sketch, select from the menubar "Sketch->Import Library->LiquidCrystal". Once the library is imported, an '#include <LiquidCrystal.h>' line will appear at the top of your Sketch. you will also need to include the SPI library. (in other words just as you would use the...
