Introduction: RFID Security Access System

Materials Requirements:

Arduino Board - https://goo.gl/9UVL82

RFID RC522 Module - https://goo.gl/yWkt8U

Servo Motor - https://goo.gl/yWkt8U

LED Kit - https://goo.gl/yWkt8U

Buzzer - https://goo.gl/yWkt8U

F to M Jumper - https://goo.gl/yWkt8U

Breadboard - https://goo.gl/yWkt8U

Get the MFRC522 Library here: https://goo.gl/CXKrqt

Step 1: Connection of RFID Module to Arduino Uno

SDA > PIN 10

SCK > PIN 13

MOSI > PIN 11

MISO > PIN 12

IRO > NOT CONNECTED

GND > GND

RST > PIN 9

3.3V > 3.3V

Connection of the Servo motor, LED and Buzzer.

Servo Motor: Orange > PIN3

Red > 5V

Brown > GND

Step 2: Connection of Breadboard With LED and Buzzer.

Red LED short leg > GND

Red LED long leg > PIN4 Yellow LED short leg > GND Yellow LED long leg > PIN5 Buzzer short leg > GND

Buzzer long leg > PIN2

Copy and upload the codes that I write to the Arduino uno then If its successfully uploaded open the serial monitor in tools section of the Arduino IDE then tap the RFID that you want to have an access then copy the UID of the respected RFID card then place it to the codes. then re-upload the codes with the UID card details. Note: You need to install the RFID library that you can download from the link above.

Step 3: Codes

#include

#include #include #define SS_PIN 10 #define RST_PIN 9 #define LED_G 5 //define green LED pin #define LED_R 4 //define red LED #define BUZZER 2 //buzzer pin MFRC522 mfrc522(SS_PIN, RST_PIN); // Create MFRC522 instance. Servo myServo; //define servo name void setup() { Serial.begin(9600); // Initiate a serial communication SPI.begin(); // Initiate SPI bus mfrc522.PCD_Init(); // Initiate MFRC522 myServo.attach(3); //servo pin myServo.write(0); //servo start position pinMode(LED_G, OUTPUT); pinMode(LED_R, OUTPUT); pinMode(BUZZER, OUTPUT); noTone(BUZZER); Serial.println("Put your card to the reader..."); Serial.println();

} void loop() { // Look for new cards if ( ! mfrc522.PICC_IsNewCardPresent()) { return; } // Select one of the cards if ( ! mfrc522.PICC_ReadCardSerial()) { return; } //Show UID on serial monitor Serial.print("UID tag :"); String content= ""; byte letter; for (byte i = 0; i < mfrc522.uid.size; i++) { Serial.print(mfrc522.uid.uidByte[i] < 0x10 ? " 0" : " "); Serial.print(mfrc522.uid.uidByte[i], HEX); content.concat(String(mfrc522.uid.uidByte[i] < 0x10 ? " 0" : " ")); content.concat(String(mfrc522.uid.uidByte[i], HEX)); } Serial.println(); Serial.print("Message : "); content.toUpperCase(); if (content.substring(1) == "XX XX XX XX") //change here the UID of the card/cards that you want to give access { Serial.println("Authorized access"); Serial.println(); delay(500); digitalWrite(LED_G, HIGH); tone(BUZZER, 500); delay(300); noTone(BUZZER); myServo.write(180); delay(5000); myServo.write(0); digitalWrite(LED_G, LOW); } else { Serial.println(" Access denied"); digitalWrite(LED_R, HIGH); tone(BUZZER, 300); delay(1000); digitalWrite(LED_R, LOW); noTone(BUZZER); } }

    Can you explain to me void loop part! Please
