Tutorial Seguridad Biometrica Huella Digital

En este tutorial usamos un modulo biometrico de huella digital para brindar seguridad a nuestros proyectos.

Requisitos:

1. Computadora (mac)
2. Arduino UNO
3. FPS GT511-c1R FPS
4. Resistores
5. Breadboard
6. Arduino IDE (https://www.arduino.cc/en/Main/Software)

El setup continua igual.  Ahora cambiamos el codigo para registrar huellas digitales en el modulo.

El código:

[code]#include “FPS_GT511C3.h”
#include “SoftwareSerial.h”
//FPS connected to pin 4 and 5 – see previous schemas
FPS_GT511C3 fps(4, 5);
void setup(){
Serial.begin(9600);
//display messages on the classical serial teminal – DEBUG
fps.UseSerialDebug = true;
Serial.println(“before open”);
fps.Open();
//call Enroll to add fingerprint
Serial.println(“before enroll”);
enroll();
}
void enroll(){
// get the first available id for new finger print
int enrollid = 0;
bool usedid = true;
Serial.println(“before while”);
while (usedid == true){
usedid = fps.CheckEnrolled(enrollid);
if (usedid==true) enrollid++;
}
Serial.println(“before enrollstart”);
//enrollment start here with the first free id
fps.EnrollStart(enrollid);
Serial.print(“Press finger to Enroll #”);
Serial.println(enrollid);
// ***** FIRST MEASURE *****
// wait for finger press
while(fps.IsPressFinger() == false) delay(100);
bool bret = fps.CaptureFinger(true);
int iret = 0;
if (bret != false){
//has a finger print captured
Serial.println(“Remove finger”);
// Enroll step 1
fps.Enroll1();
//wait for finger removed
while(fps.IsPressFinger() == true) delay(100);
// ***** SECOND MEASURE *****
// Now we need to check the finger print
// wait for finger press
Serial.println(“Press same finger again”);
while(fps.IsPressFinger() == false) delay(100);
bret = fps.CaptureFinger(true);
if (bret != false){
Serial.println(“Remove finger”);
//enroll step 2
fps.Enroll2();
//wait for finger removed
while(fps.IsPressFinger() == true) delay(100);
// ***** THIRD MEASURE *****
//Check Again the finger print
Serial.println(“Press same finger yet again”);
while(fps.IsPressFinger() == false) delay(100);
bret = fps.CaptureFinger(true);
if (bret != false){
Serial.println(“Remove finger”);
iret = fps.Enroll3();
if (iret == 0){
//*** SUCCESS third measure are the same -> NOW finger print is stored
Serial.println(“Enrolling Successfull”);
}else{
//*** FAIL For some reason -> NOTHING STORED
Serial.print(“Enrolling Failed with error code:”);
Serial.println(iret);
}
}
else Serial.println(“Failed to capture third finger”);
}
else Serial.println(“Failed to capture second finger”);
}
else Serial.println(“Failed to capture first finger”);
}
//loop is useless here
void loop(){
delay(100000);
}[/code]

Al conectar la UNO podemos registrar nuestra huella digital.
