I'm working with the fingerprint sensor from Adafruit. I would like some help before registering your user ID, I wish he would review research on the basis of sensor data, not to overwrite any ID.
My logic is this:
But I realize that it gives permission to re-register the same ID already registered.if (id == finger.fingerID) {
Serial.println ("Existing Number:");
Serialprintln (id);
return enroll();
}
I would like to help.
Thank you!
