I am using the RFID Tag Reader ID12 bought at Sparkfun plugged in a Arduino Due.
According to the specs (https://www.sparkfun.com/datasheets/Sensors/ID-12-Datasheet.pdf), pin 10 is a LED/Buzzer output.
Is it ok to connect pin 10 directly to an arduino due pin and attach an interrupt to it ?
I would like to know exactly when a card is waved by the sensor so I can treat the event.
Any help or pointers are greatly appreaciated!
