How To Setup Raspberry and RFID RC522 With very simple

Setup the RFID RC522 to Raspi like this:

- SDA connects to GPIO8 (Physical Pin 24)

- SCK connects to GPIO11 (Physical Pin 23)

- MOSI connects to GPIO10 (Physical Pin 19)

- MISO connects to GPIO9 (Physical Pin 21)

- GND connects to Breadboard Ground Rail. (20)

- RST connects to GPIO25 (Physical Pin 22)

- 3.3v connects to 3.3v (Physical Pin 1)

Enabled SPI (Interfaces)

pi@pi:~ $ sudo raspi-config

enabled SPI and reboot

pi@pi:~ $ sudo reboot

Test

pi@pi:~ $ lsmod | grep spi

spidev                 20480  0

spi_bcm2835            20480  0

Install

pi@pi:~ $ sudo pip3 install spidev

Make Directory and Python file

pi@pi:~ $ mkdir ~/pi-rfid

pi@pi:~ $ nano ~/pi-rfid/read.py

#!/usr/bin/env python

import RPi.GPIO as GPIO

from mfrc522 import SimpleMFRC522



reader = SimpleMFRC522()

try:

        id, text = reader.read()

        print(id)

        print(text)

finally:

        GPIO.cleanup()

Save it and test the file and tap the card
