GPIO Soundboard with just one button [closed]

Question

i am trying to program a soundboard in python using gpiozero and a single button. Every time you press the button it should play the next sound. It almost works, but unfortunately not satisfactory yet.

Can you help me?

import pygame
from time import sleep
from gpiozero import Button
from signal import pause


pygame.init()

button = Button(4)

snd1 = pygame.mixer.Sound("/home/pi/test.wav")
snd2 = pygame.mixer.Sound("/home/pi/test2.wav")
snd3 = pygame.mixer.Sound("/home/pi/test3.wav")
snd4 = pygame.mixer.Sound("/home/pi/test4.wav")

while True:
    button.when_pressed = snd1.play
    button.when_pressed = snd2.play
    button.when_pressed = snd3.play
    button.when_pressed = snd4.play

pause()

Answer 1

button.when_pressed should really be assigned once for simplicity. I've created a function playFile() to cycle through the sound files to be played.

Try the following:

import pygame
from time import sleep
from gpiozero import Button
from signal import pause

def playFile():
    global sndPos
    print('playFile',sndPos)
    pygame.mixer.stop()
    snds[sndPos].play()
    sndPos += 1
    if sndPos>3:
        sndPos = 0

pygame.init()

sndPos = 0
snds = [pygame.mixer.Sound("/home/pi/test.wav"),
        pygame.mixer.Sound("/home/pi/test2.wav"),
        pygame.mixer.Sound("/home/pi/test3.wav"),
        pygame.mixer.Sound("/home/pi/test4.wav")]
button = Button(4)
button.when_pressed = playFile

pause()
