How To Enroll New Fingerprint ID In Fingerprint Sensor R307 Using Arduino Uno By Technoesolution | #arduinotutorial

January 30, 2022

Description

Hello, In a previous article I explain "How to delete unwanted finger ID from sensor" & In this article, I will show you how to "Enroll New fingerprint ID in fingerprint Sensor Using Arduino". To perform this tutorial first add Adafruit Fingerprint ID in your Arduino IDE. I have already explained how to add this library in Arduino IDE you can check out the previous article. I provide the Library link below. I have already made a tutorial video on this topic you can refer to my Youtube Channel for the tutorial.

Watch out the video If reading bores you.

void loop()                     // run over and over again
{
  Serial.println("Please type in the ID # (from 1 to 127) you want to delete...");
  uint8_t id = readnumber();
  if (id == 0) {// ID #0 not allowed, try again!
     return;
  }

  Serial.print("Deleting ID #");
  Serial.println(id);

  uint8_t p = -1;
  
  p = finger.deleteModel(id);

  if (p == FINGERPRINT_OK) {
    Serial.println("Deleted!");
  } else if (p == FINGERPRINT_PACKETRECIEVEERR) {
    Serial.println("Communication error");
    return p;
  } else if (p == FINGERPRINT_BADLOCATION) {
    Serial.println("Could not delete in that location");
    return p;
  } else if (p == FINGERPRINT_FLASHERR) {
    Serial.println("Error writing to flash");
    return p;
  } else {
    Serial.print("Unknown error: 0x"); Serial.println(p, HEX);
    return p;
  }
