I finally found a way to use your fingerprint sensor using this library : Adafruit_Fingerprint.h
I tried this :


#include <Adafruit_Fingerprint.h>
#include <HardwareSerial.h>

HardwareSerial mySerial(0);
Adafruit_Fingerprint finger = Adafruit_Fingerprint(&mySerial);

I solved it with this code ...
