 **PICCprogrammer.ino** - sketch used with Arduino to program RFID-tags. Open Serial monitor and follow instructions.
+
 **PICCreader-One_LED.ino** - sketch used in standalone mode with LED connected to GPIO 5. Output is dim when no tag is present and high when tag is present
+
 **PICCreader-Two_LED.ino** - sketch used in standalone mode with one LED connected to GPIO 5 and another to GPIO 6. Output is LOW on GPIO 5 and HIGH on GPIO 6 when tag is present and HIGH on GPIO 5 and LOW on GPIO 6 when tag is not present.
