Hi all I want to modify fingerprint code to control servo

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

int getFingerprintIDez();

// 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...");
}

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);
  return finger.fingerID;

and servo code

#include <Servo.h>

 Servo myservo;  // create servo object to control a servo
// twelve servo objects can be created on most boards

int pos = 0;    // variable to store the servo position

void setup() {
   myservo.attach(9);  // attaches the servo on pin 9 to the servo object
}

void loop() {
   for (pos = 0; pos <= 180; pos += 1) { // goes from 0 degrees to 180 degrees
     // in steps of 1 degree
     myservo.write(pos);              // tell servo to go to position in variable 'pos'
     delay(15);                       // waits 15ms for the servo to reach the position
   }
   for (pos = 180; pos >= 0; pos -= 1) { // goes from 180 degrees to 0 degrees
     myservo.write(pos);              // tell servo to go to position in variable 'pos'
     delay(15);                       // waits 15ms for the servo to reach the position
   }
}

how can I merge them.

hope I found someone can help.

You haven't said what you want the merged code to do.

how can I merge them.

I want to open door lock by finger print like {http://www.instructables.com/id/Arduino-Fingerprint-Lock/}

I install it files but it say that it dose not include any valid library.

I have it posted on {http://forum.arduino.cc/index.php?topic=387646.0} but no one answer me so I thought to

merge them to do the same.

Its good also to think outside the box ... that is, draw a box, think about what you want the project to do, then label the required input pins and output pins. Follow reply#2 and I think you're all set.

Has no one ever told you instructables are crap. They are written by people with an over inflated idea of their own ability.
Here we are fed up with acting as a help desk for instructables.

t I have problem with the servo

And that problem is. . . ?

9

it does not move only make sound from the time of uploading the sketch.

but when I'm using the servo example alone it work fine.

10

In loop you call getFingerprintIDez(). The first thing in that function is to move the servo from 0 degrees to 180 degrees at a rate of 1 degree per 1.5 seconds. That will take about 4.5 minutes to complete. Then 180 to 0' another 4.5 minutes. Delay(1500) is not delay 15milliseconds.

11

Thank you but I still have the servo looping how can I make it work one time for every fingerprint.

Is there any way than make the power supply with push button and relay which make the supply for the board for limited time then turns off?

12

Just guessing, but it seems that there is a clue where to put code to run when a valid fingerprint is detected

// found a match!

I can't test it but it looks like this might work (replace getFingerprintIDez()) .

// 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);

  for (pos = 0; pos <= 180; pos += 1)  // goes from 0 degrees to 180 degrees
  {                                     // in steps of 1 degree
    myservo.write(pos);                  // tell servo to go to position in variable 'pos'
    delay(15);                         // waits 15ms for the servo to reach the position
  }
  for (pos = 180; pos >= 0; pos -= 1)    // goes from 180 degrees to 0 degrees
  {
    myservo.write(pos);                  // tell servo to go to position in variable 'pos'
    delay(15);                         // waits 15ms for the servo to reach the position
  }

  return finger.fingerID;
}

Thank you it work fine.

the sensor goes to sleep mode after while.

I thought to have relay to the sensor V+ with button is there any better way built in function in the board.

14

Is this the sensor that you have? Adafruit fingerprint sensor

I looked through that manual and the Adafruit fingerprint library header and found no reference to sleep mode.

15

I got it from aliexpress it turn of after while
