Button Presses in Certain Time Frame

[MsCheeseyPuff]

I made a sound board and I wanted to improve it, so I want to change libraries with the amount of button presses(library A with one press and library B with two). I also have an LED to show that the button has been pressed. How do I count the button presses and have it within a time frame? Here's my code:

import pygame.mixer from time import sleep import RPi.GPIO as GPIO from sys import exit GPIO.setmode(GPIO.BCM) GPIO.setwarnings(False) GPIO.setup(21, GPIO.IN, pull_up_down=GPIO.PUD_UP) GPIO.setup(19, GPIO.IN, pull_up_down=GPIO.PUD_UP) GPIO.setup(7, GPIO.IN, pull_up_down=GPIO.PUD_UP) GPIO.setup(8, GPIO.IN, pull_up_down=GPIO.PUD_UP) GPIO.setup(9, GPIO.IN, pull_up_down=GPIO.PUD_UP) GPIO.setup(10, GPIO.IN, pull_up_down=GPIO.PUD_UP) GPIO.setup(20, GPIO.IN, pull_up_down=GPIO.PUD_UP) GPIO.setup(6, GPIO.OUT) GPIO.setup(5, GPIO.OUT) GPIO.setup(24, GPIO.OUT) GPIO.setup(23, GPIO.OUT) GPIO.setup(27, GPIO.OUT) GPIO.setup(17, GPIO.OUT) GPIO.setup(22, GPIO.OUT) PAUSE = 0.5 #var = 1 presses = 0 GPIO.output(6, False) GPIO.output(5, False) GPIO.output(24, False) GPIO.output(23, False) GPIO.output(27, False) GPIO.output(17, False) GPIO.output(22, False) print ('Soundboard Ready') def lib_a():    global presses    presses1 = presses + 1 def lib_b():    global presses    presses2 = presses + 2 while True: ##

thank you, sorry I'm new to all this

def button_1():    if (GPIO.input(21) == False and lib_a()):        soundChannel1.play(sound_1)        while pygame.mixer.get_busy() == True:            GPIO.output(6, True)        else:            GPIO.output(6, GPIO.LOW)    if (GPIO.input(21) == False and lib_b()):        soundChannel7.play(sound_7)        while pygame.mixer.get_busy() == True:            GPIO.output(6, True)        else:            GPIO.output(6, GPIO.LOW)

I'm confused, does any sound come out at all right now?  lib_a() and lib_b() don't return anything, so your if blocks should never run.

This is unrelated, but instead of having a different function for each button with a bunch of hardcoded values for which pin it is and which sound file, your life would be much better if all of those were really just a single function.  Also, don't use exit(), since the rest of your code will never run (you'll never cleanup the pins at the end).  Something like:

# first, declare the pins sounds = {    21: {        "sound": pygame.mixer.Sound('/home/pi/Documents/PiSounds/applause.wav'),        "alt-sound": pygame.mixer.Sound('/home/pi/Documents/PiSounds/buzzer.wav'),        "channel": pygame.mixer.Channel(1),        "alt-channel": pygame.mixer.Channel(1),        "out-pin": 6    } # etc } def button_pressed(in_pin):    sound = sounds[in_pin]     if (GPIO.input(in_pin) == False and lib_a()):         sound["channel"].play(sound["sound"])         while pygame.mixer.get_busy() == True:             GPIO.output(sound["out-pin"], True)         else:             GPIO.output(sound["out-pin"], GPIO.LOW)    if (GPIO.input(in_pin) == False and lib_b()):         sound["alt-channel"].play(sound["alt-sound"])         while pygame.mixer.get_busy() == True:             GPIO.output(sound["out-pin"], True)         else:             GPIO.output(sound["out-pin"], GPIO.LOW) # now to listen for presses... running = True while running:    try:         for pin in sounds:             if not GPIO.input(pin):                 button_pressed(pin)         sleep(1)    except KeyboardInterrupt:         running = False GPIO.cleanup()

Thank you so much!! :)
