I'm trying to create a security door system that uses an RFID and fingerprint sensor (Adafruit) to allow/deny access to a door. I have the fingerprint sensor and RFID hooked up to an LED, but the code isn't working very well. I want the LED to light only and only when both fingerprints and RFID are verified. Here is my preliminary code.
//HEADERFILES
#include <SPI.h> //rfid
#include <MFRC522.h>//rfid
#include <Adafruit_Fingerprint.h> //FINGERPRINT
#include <SoftwareSerial.h> //FINGERPRINT
#include<stdint.h> //FINGERPRINT
//rfid settings
#define RST_PIN 9 // rfid pin 9 RST_pin
#define SS_PIN 10 // rfid pin 10 SS_pin
MFRC522 mfrc522(SS_PIN, RST_PIN); // Create MFRC522 instance
String read_rfid;
String ok_rfid_1 = "cbb427b2"; //white card
String ok_rfid_2 = "0ebb14f39"; //blue key chain
//fingerprint settings
int getFingerprintIDez();
// pin #2 is IN from sensor (GREEN wire)
// pin #3 is OUT from arduino (YELLOW wire)
SoftwareSerial mySerial(2, 3);
//activates serial communication on pin 2 & 3
Adafruit_Fingerprint finger = Adafruit_Fingerprint(&mySerial);
//output garage door pin
int door = 7; //motor to door
void dump_byte_array(byte * buffer , byte bufferSize) { //why so important
read_rfid = "";
for (byte i = 0; i < bufferSize; i++) {
read_rfid = read_rfid + String(buffer[i], HEX);
}
}
void setup() {
//RFID setup
Serial.begin(9600);
// Initialize serial communications with the PC
while (!Serial);
// Do nothing if no serial port is opened (added for Arduinos based on ATMEGA32U4)
finger.begin(57600);
SPI.begin(); // Init SPI bus
mfrc522.PCD_Init(); // Init MFRC522 RFID
pinMode (door, OUTPUT);
//FINGERPRINT setup
{
while (!Serial); // For Yun/Leo/Micro/Zero/...
if (finger.verifyPassword()) {
Serial.println("Found fingerprint sensor!");
} else {
Serial.println("Did not find fingerprint sensor :(");
while (1);
}
Serial.println("Waiting for valid finger...");
}
}
// 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;
}
}
//DOOR/OUTPUT PIN PROPERTIES CHANGE TO REFLECT HOW FAST AND HOW LONG MOTOR PULLS DOOR USING DIGITALWRITE; BREAK.. //USING LED FOR NOW
void open_door() {
digitalWrite (door, HIGH);
delay (2000);
digitalWrite (door, LOW);
}
void loop() {
// RFID LOOP SETTINGS `
if ( ! mfrc522.PICC_IsNewCardPresent()) { // Look for new cards
return;
}
if ( ! mfrc522.PICC_ReadCardSerial()) { // Select one of the c ards
return;
}
dump_byte_array(mfrc522.uid.uidByte, mfrc522.uid.size);
Serial.println(read_rfid);
// FINGERPRINT LOOP SETTINGS
getFingerprintID(); // start fingerprint sensor
delay(100);
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;
}
p = finger.fingerFastSearch();
if (p == FINGERPRINT_OK && read_rfid == ok_rfid_1) {
Serial.println(ok_rfid_1);
open_door();
}
}
And this is the error I am getting
Arduino: 1.8.1 (Windows 10), Board: "Arduino/Genuino Uno"
fingerprint:127: error: expected unqualified-id before '{' token
{
^
exit status 1
expected unqualified-id before '{' token
This report would have more information with
"Show verbose output during compilation"
option enabled in File -> Preferences.
I am new to this so please bear with me and explain in childish manner if possible.
