Python • Re: Infinite Loop

Hi all,

I have a Raspberry Pi 3B+ and I use it to activate a .wav file when motion is detected. I want it to have an infinite loop, where it can run the "while True" part of the code again and again. How can I do that? Also, I am a beginner for this coding language, so can someone please check my code that it's all correct?

Code:

from gpiozero import MotionSensorimport pygameimport time#VariablesPIR_PIN = (4)#File Setuppath = "/home/pi49366/12_drum_sounds/"sound_files = ["bass_hit_c.wav", "bd_tek.wav", "two_crickets.wav"]#GPIO SETUPGPIO.setup(PIR_PIN, GPIO.IN) #pygame Setuppygame.mixer.init()speaker_volume = 0.5 #50% volumepygame.mixer.music.set_volume(speaker_volume)# Initialize Pygame pygame.mixer.init()def play_sound():     pygame.mixer.music.load(path + sound_files) # Change to your .wav file path pygame.mixer.music.play()def is_within_time_range(start_time, end_time):    current_time = datetime.now().time()    return start_time <- current_time <= end_time#Defines time rangestart_time = datetime.strptime("16:30", "%H:%M").time()end_time = datetime.strptime("06:30", "%H:%M").time()if time == end_time:    print("Total Hours On: 14 Hours 00 Minutes, 840 Minutes")    print("Waiting For Motion...")while True:    if GPIO.setup(PIR_PIN):        print("Motion Detected, playing sound!")    play_sound()    time.sleep(0.1) #Small delay to avoid excessive CPU useage                finally:        GPIO.cleanup() #Clean up GPIO on exit

Thanks.

That's just what a Python while True: statement does. https://docs.python.org/3/reference/com ... -statement

Frankly, it is a confused mess.

You have chosen gpiozero as your Python library to handle GPIO pins, but never make use of it.

But you refer to methods named GPIO.something which will fail because you haven't defined what GPIO is.

And if you were using the RPi.GPIO library, the method GPIO.setup is used for initialisation, not for checking the status of a GPIO pin.

(I recommend the use of gpiozero in preference to RPi.GPIO: it is what Raspberry Pi mention in their own Documentation. https://www.raspberrypi.com/documentati ... rom-python )
