A short example of how to read 125 kHz RFID tags using an Arduino and a RMD6300 RFID module

See a video here on how it works in action [Youtube] (http://www.youtube.com/watch?v=u8YD3-BrHv0)

Required hardware

• Arduino Uno (or other Arduino)
• 125Khz RFID module RDM6300 - UART
• Breadboard, cables, LEDs

How to use

• Simply plug the antenna, as well as the power, ground and TX pins of the RFID module to the Arduino (you can find the pins description in the datasheet). The TX pin of the module should connect to the RX pin of the Arduino.
• To use the LEDs as success/error indicators, plug two LEDs to the Arduino (in our code, we use pin 10 and 13)
• Using the Arduino IDE, compile and upload the code to the Arduino. Note that you have to unplug the cable connecting to the RX pin of the Arduino to be able to upload the code.
• Put one of your RFID tags close to the antenna and watch! You can use the serial monitor of the Arduino IDE (Ctrl+Shift+M) to see the messages we are printing, and note down the IDs of your tags if you don't know them.
