Enrolling your fingerprint

The first thing that we have to do is enroll at least one fingerprint so that it can be later recognized by the sensor. We will do that in this section. Here is most of the code for this section:

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

// Fingerprint enroll function
uint8_t getFingerprintEnroll(uint8_t id);

// Software Serial instance
SoftwareSerial mySerial(2, 3);

// Fingerprint sensor instance
Adafruit_Fingerprint finger = Adafruit_Fingerprint(andmySerial);

void setup() 
{
  // Start serial
  Serial.begin(9600);
  Serial.println("fingertest");

  // Set the data rate for the sensor serial port
  finger.begin(57600);

  // Verify that sensor is present
  if (finger.verifyPassword()) {
    Serial.println("Found fingerprint sensor!");
  } else {
    Serial.println("Did not find fingerprint sensor :(");
    while (1);
  }
}

void loop()
{
  // Wait for fingerprint ID
  Serial.println("Type in the ID # you want to...
