Beginners • Using threading.Event to control my GPIO Pins

Code:

import threadingfrom gpiozero import Buttonfrom mfrc522 import SimpleMFRC522from signal import pauseimport RPi.GPIO as GPIOimport timeGPIO.setwarnings(False)button = Button(5, bounce_time=0.2)  reader = SimpleMFRC522()# Event object to control RFID readingrfid_reading_event = threading.Event()# Function to toggle RFID readingdef toggle_rfid_reading():    while True:        rfid_reading_event.wait()  # Wait for the event to be set        id, _ = reader.read()        print(f"RFID Tag ID: {id}")        time.sleep(2)# Start the RFID reading threadrfid_reading_thread = threading.Thread(target=toggle_rfid_reading)rfid_reading_thread.start()# Variable to track the RFID reading stateis_rfid_reading = False# Callback function for button pressdef button_pressed():    global is_rfid_reading    print("Button pressed")    if is_rfid_reading:        print("Clearing event")        rfid_reading_event.clear()  # Clear the event to stop RFID reading        is_rfid_reading = False    else:        print("Setting event")        rfid_reading_event.set()  # Set the event to start RFID reading        is_rfid_reading = Truepause()

Code:

# On the first click of the buttonButton pressedSetting event# Scan several RFIDRFID Tag ID: 11616204003RFID Tag ID: 11616204003# Click the button againButton pressedClearing event# I still was able to scan an RFID but after this one, the RFID was not activated anymoreRFID Tag ID: 11616204003
