PN532 NFC RFID Tag Reader

Made with an ESP D1 Mini and PN532. It is designed to arm and disarm the alarm, and it also shows the armed status with an LED on the back (green and red depending on whether it is armed or not). The same applies to the rest as well. The letters are printed separately so they can be inserted into the enclosure and printed with transparent material, allowing the lighting from behind to be visible.
