RFID Evaluation Shield - 13.56MHz +
SM130-RFID 模組 (13.56 MHz)
我有購買以上所提及的模組套件,依照官方所提供的範例進行燒入使用,設備有正常運作,但始終無法顯示已感應到的卡片資訊,在此麻煩各位先進提供協助
以下為提供官方提供的程式碼。

RFID Eval 13.56MHz Shield example sketch v10
Aaron Weiss, aaron at sparkfun dot com
OSHW license: http://freedomdefined.org/OSHW
works with 13.56MHz MiFare 1k tags
Based on hardware v13:
D7 -> RFID RX
D8 -> RFID TX
D9 -> XBee TX
D10 -> XBee RX
Note: RFID Reset attached to D13 (aka status LED)
Note: be sure include the SoftwareSerial lib, http://arduiniana.org/libraries/newsoftserial/
Usage: Sketch prints 'Start' and waits for a tag. When a tag is in range, the shield reads the tag,
blinks the 'Found' LED and prints the serial number of the tag to the serial port
and the XBee port.
