RFID 125 kHz Reader with 1602 display
RFID reader for 125 kHz with 1602 display on Arduino. This is how our setup at the American International School Vietnam looks like:

Building steps
- Connect the RFID kit to the Arduino, as well as the 1602 with the I2C adapter and 4 wires
- Connections according to link will follow
- Upload the software found in the link above. Don’t forget the library for the hd44780 controller and the hd44780_I2C expansion set. Files are located under library.
Got to the wiki for further details. We work on a new RTL-SDR to visualize the communication between the cards on the 125 kHz and 13.56 MHz frequency.
