A quick demonstration of reading and reacting to different colored Kyber Crystals from Star Wars Galaxy's Edge.
I left the crystals in their packages because I'm lazy. This will still work with the crystals outside of their case.
I'm using an Arduino Uno, an RDM6300 RFID module, and an RGB LED.
The code used in this demo can be found here:

The RDM6300 sends RFID information via serial communications to the arduino which then sets the RGB LED to a color that corresponds to the kyber crystal being read.
