On this instructable I will try to show how to interface a RFID sensor with the Arduino. I am using the RFID sensor from seeedstudio the serial version of it. There are a few parts you will gonna need. I also bought some RFID keys.
UPDATE: Now it works with IDE 021
Step 1: What you gonna need?
- Arduino Board
- RFID Sensor from seeedstudios
- RFID tags (125kHz) from seeedstudios
