  • I'm having a tough time reading this chip from an Arduino Duemilanove. I have it connected as the datasheet says (confirmed at this page) wired to the Rx pin (pin 0) of the Arduino. Yet when I run the simple relay code
    if(Serial.available() > 0) {
    val = Serial.read();
    Serial.print(val, BYTE);
    I get bupkis in the Serial Monitor, or I get a constant stream of a single character (I think it was 'ƥ' at 9600bps). The relay blinks when the card is held close by.
    Does it sound like I somehow burned out the chip? Is there any good way to test?
    Thank you,
