Introduction :

In this article we going to implement one IOT base project Python Code For Attendance System Using Arduino With RFID. In the previous article we clearly see How to RFID data display from serial port to laptop or pc screen using python software.

so in this project we are use RFID base system for student attendance purposed.

Python Code For Attendance System Using Arduino With RFID

pre- requirement :

  1.  Arduino IDE
  2. Arduino UNO
  3. RFID- RC522
  4. Python compiler
  5.  Installation of XAMPP server: 

 In this project we are using phpMyAdmin that is the web interface of MySQL server 

If you want to installed it then use command: sudo apt-get install phpMyAdmin.

You need to connect ethernet shield first as shown and then you need to make the connection of RFID with arduino uno. if you dont’t know about this then please goes to arduino official site and refer it. (link is available below)

Detailed Pin connection for RFID and Arduino uno

MOSI 11 51

MISO 12 50

SCK 13 52

RST 9 9

SDA(SS) 4/10 4/53

VCC 3.3 v 3.3v

GND GND GND

Remember: IRQ is not nee to connect.

Step 1: First you need to make the all physical connection between Arduino UNO and RFID reader.

Step 2: Then you need to install supporting Arduino library  

You need to install one library for rfid rc522

Step 3: Compile all program (python /Arduino)

Arduino code (Python Code For Attendance System Using Arduino With RFID)

#include <SPI.h>
#include<MFRC522.h>
#include <Ethernet.h>

#define SS_PIN 10 
#define RST_PIN 9
#define No_Of_Card 3

  {151,94,80,84}              //RFID NO-3

int j=0;

void setup() {
  Serial.begin(9600);

  SPI.begin();

  // Stop encryption on PCD

Python Code For Attendance System Using Arduino With RFID

Python code to push data to phpMyAdmin 

import serial 
import MySQLdb
import time

#establish connection to MySQL. You'll have to change this for your database.
dbConn = MySQLdb.connect("localhost","root","","Your DB Name") or die ("could not connect to database")
#open a cursor to the database
cursor = dbConn.cursor()

device = 'COM6' #this will have to be changed to the serial port you are using
try:
  print "Trying...",device 
  arduino = serial.Serial(device, 9600) 
except: 
  print "Failed to connect on",device
while True:
    time.sleep(1)
    try:
        data=arduino.readline()
        print data
        pieces=data.split(" ")
        try:
            cursor=dbConn.cursor()
            cursor.execute("""INSERT INTO <your table name> (ID,Member_ID,allowed_members) VALUES (NULL,%s,%s)""", (pieces[0],pieces[1]))
            dbConn.commit()
            cursor.close()
        except MySQLdb.IntegrityError:
            print "failed to insert data"
        finally:
            cursor.close()
    except:
        print "Processing"
