TUTORIAL MENGAKSES ARDUINO FINGERPRINT

       Pada kesempatan kali ini saya akan menjelaskan mengenai bagaimana cara mengakses modul fingerprint dengan menggunakan arduino. jadi alat ini bisa mengidentifikasi jari yang didaftarkan pada sensor fingerprint. alat ini sangat tepat sekali untuk projek smart door lock atau project lainnya yang menggunakan fingerprint sebagai ID aksesnya. untuk lebih jelasnya berikut adalah komponen dan contoh programnya. 

a. Arduino Mega

b. Fingerprint Modul

c. Program Arduino IDE

#include <Adafruit_Fingerprint.h>
#include <SoftwareSerial.h>

int getFingerprintIDez();

//arduino mega
// pin #10 is IN from sensor (GREEN wire)
// pin #11 is OUT from arduino  (WHITE wire)
SoftwareSerial mySerial(10, 11);


//arduino uno
// pin #2 is IN from sensor (GREEN wire)
// pin #3 is OUT from arduino  (WHITE wire)
//SoftwareSerial mySerial(2, 3);

Adafruit_Fingerprint finger = Adafruit_Fingerprint(&mySerial);

void setup() 
{
  pinMode(13,OUTPUT);
  digitalWrite(13,LOW);
 
  Serial.begin(9600);
  Serial.println("fingertest");

  // set the data rate for the sensor serial port
  finger.begin(57600);
 
  if (finger.verifyPassword()) {
    Serial.println("Found fingerprint sensor!");
  } else {
    Serial.println("Did not find fingerprint sensor :(");
    while (1);
  }
  Serial.println("Waiting for valid finger...");
}

void loop()                     // run over and over again
{
  getFingerprintIDez();
  delay(50);            //don't ned to run this at full speed.
}

uint8_t getFingerprintID() {
  uint8_t p = finger.getImage();
  switch (p) {
    case FINGERPRINT_OK:
      Serial.println("Image taken");
      break;
    case FINGERPRINT_NOFINGER:
      Serial.println("No finger detected");
      return p;
    case FINGERPRINT_PACKETRECIEVEERR:
      Serial.println("Communication error");
      return p;
    case FINGERPRINT_IMAGEFAIL:
      Serial.println("Imaging error");
      return p;
    default:
      Serial.println("Unknown error");
      return p;
  }

  // OK success!

  p = finger.image2Tz();
  switch (p) {
    case FINGERPRINT_OK:
      Serial.println("Image converted");
      break;
    case FINGERPRINT_IMAGEMESS:
      Serial.println("Image too messy");
      return p;
    case FINGERPRINT_PACKETRECIEVEERR:
      Serial.println("Communication error");
      return p;
    case FINGERPRINT_FEATUREFAIL:
      Serial.println("Could not find fingerprint features");
      return p;
    case FINGERPRINT_INVALIDIMAGE:
      Serial.println("Could not find fingerprint features");
      return p;
    default:
      Serial.println("Unknown error");
      return p;
  }
 
  // OK converted!
  p = finger.fingerFastSearch();
  if (p == FINGERPRINT_OK) {
    Serial.println("Found a print match!");
  } else if (p == FINGERPRINT_PACKETRECIEVEERR) {
    Serial.println("Communication error");
    return p;
  } else if (p == FINGERPRINT_NOTFOUND) {
    Serial.println("Did not find a match");
    return p;
  } else {
    Serial.println("Unknown error");
    return p;
  }  
 
  // found a match!
  Serial.print("Found ID #"); Serial.print(finger.fingerID);
  Serial.print(" with confidence of "); Serial.println(finger.confidence);
}

// returns -1 if failed, otherwise returns ID #
int getFingerprintIDez() {
  uint8_t p = finger.getImage();
  if (p != FINGERPRINT_OK)  return -1;

  p = finger.image2Tz();
  if (p != FINGERPRINT_OK)  return -1;

  p = finger.fingerFastSearch();
  if (p != FINGERPRINT_OK)  return -1;
 
  // found a match!
  Serial.print("Found ID #"); Serial.print(finger.fingerID);
  Serial.print(" with confidence of "); Serial.println(finger.confidence);


  if(finger.fingerID == 0){
  Serial.println("Yanuar");
  digitalWrite(13,HIGH);
  }
 
  if(finger.fingerID == 1){
  Serial.println("JONI");
  digitalWrite(13,HIGH);
  }
 
  if(finger.fingerID == 2){
  Serial.println("STEVAN");
  digitalWrite(13,HIGH);
  }

  return finger.fingerID;
}
