RF-ID DOOR LOCKING SYSTEM || REAL TIME PROJECT

RF-ID DOOR LOCKING SYSTEM

HEY GUYS I CAME UP WITH A NEW REAL TIME PROJECT RF-ID DOOR LOCKING SYSTEM WITH ARDUINO.

THIS PROJECT CAN BE USED IN COLLEGES,SCHOOLS,OFFICE,HOMES,SHOPS ,ETC.

COMPONENTS REQUIRED:-

1. ARDUINO NANO.

2. RFID-RC522 MODULE.

3. RFID TAGS.

4. ZERO PCB.

5. BUZZER.

6. LED'S (GREEN, RED).

7. PUSH BUTTON.

8. FEMALE BERG STRIPE PINS.

9. JUMPER WIRES.

10. 16 X 2 LCD DISPLAY.

CIRCUIT :-

LIBRARY:-

1. RF-ID-MASTER:-

https://github.com/miguelbalboa/rfid

2. DOWNLOAD LIQUID CRYSTAL LIBRARY :-  

https://github.com/arduino-libraries/LiquidCrystal

SOURCE CODE:-

1. DUMPINFO CODE

UPLOAD THIS CODE FOR SCANNING YOU ID CARDS AND TAGS.

#include <SPI.h>

#include <MFRC522.h>

#define RST_PIN  9 

#define SS_PIN  10 

MFRC522 mfrc522(SS_PIN, RST_PIN); 

void setup() {

Serial.begin(9600);

while (!Serial);

SPI.begin();

mfrc522.PCD_Init();

delay(4);

mfrc522.PCD_DumpVersionToSerial();

Serial.println(F("Scan PICC to see UID, SAK, type, and data blocks..."));

}

void loop() {

if ( ! mfrc522.PICC_IsNewCardPresent()) {

return;

}

// Select one of the cards

if ( ! mfrc522.PICC_ReadCardSerial()) {

return;

}

mfrc522.PICC_DumpToSerial(&(mfrc522.uid));

}

2. 16 X 2 LCD DISPLAY CODE:

THIS CODE IS FOR CHECKING YOUR LCD DISPLAY 

//DOWNLOAD LIQUID CRYSTAL LIBRARY  https://github.com/arduino-libraries/LiquidCrystal

#include<LiquidCrystal.h>

LiquidCrystal lcd(A0, A1, A2, A3, A4, A5);//(RS, Enable, A2, A3, A4, A5)

void setup() {

// set up the LCD's number of columns and rows:

lcd.begin(16, 2);

}

void loop() {

lcd.setCursor(2,0);

lcd.print("MKINVENTIONS");

lcd.setCursor(0,1);

lcd.print("MADHAN CHIRUGURI");

}

3. RF-ID WITH 16 X 2 LCD DISPLAY CODE:-
