I grabbed the Keypad Library from the Arduino Playground and set the correct pins according to the Arduino tutorial. No such [...]

So anyway, I added my Parallax RFID card to the setup and finally worked out [...]

So I got a reply from John Ryan on the Arduino forums and he mentioned that I would need to use an interrupt to grab RFID data to ensure it did not stop my program while waiting for a tag. I banged my head around with the implementation of interrupt code but found a solution [...]

So I’ve been playing around with the Arduino now for a month or two and trying to interface it with a few of the Parallax accessories I have lying around. I’ve been meaning to post stuff here the whole time but was lazy. Anyway, here is some modified Wiring code for Arduino to use the [...]
