Fingerprint Sensor Control Relay ARDUINO

Fingerprint Sensor Control Relay ARDUINO

             Pada kesempatan kali ini saya akan menjelaskan mengenai bagaimana cara membuat sebuah alat yang menggunakan sensor fingerprint sebagai kendalinya, alat ini menggunakan 2 buah relay sebagai outputnya, untuk alat yang dikendalikan bisa bervariasi yaitu motor, lampu AC dll. alat ini cukup simple cuma yang harus diperhatikan yaitu wiring saat register finger dan saat running finger sensor. untuk program dan komponenya seperti berikut.

a. Arduino Uno

b. Sensor Fingerprint

c. Modul relay 2 Channel

d. Program Arduino IDE

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

int getFingerprintIDez();
int relay1 = 8;
int relay2 = 9;
int tanda;

//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()
{

  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...");

  pinMode(relay1,OUTPUT);
  digitalWrite(relay1,HIGH);
  pinMode(relay2,OUTPUT);
  digitalWrite(relay2,HIGH);

}

void loop()
