Interfacing Big SpaceBar Button with Raspberry Pi & perform certain task on pressing

[Ammar Ashraf]

Hi,
I am working on a project in which I have to play 5 mp3 songs in a sequence one after another. Each song has a duration of 10s. For that purpose, I am using pygame library. All is working fine but I have to add one for future in this application that is I want to start and pause these mp3 songs on pressing this BIG Button that is connected through one of the serial port of Raspberry Pi. I am a beginner level and don't know how to do this. Kindly! help me. Your help will be appreciated

Code: Select all

import time
import random
import RPi.GPIO as GPIO
import pygame
pygame.mixer.init()

# setting a current mode
GPIO.setmode(GPIO.BCM)
#removing the warings 
GPIO.setwarnings(False)
#creating a list (array) with the number of GPIO's that we use 
pins = [16,20,21] 

#setting the mode for all pins so all will be switched on 
GPIO.setup(pins, GPIO.OUT)
GPIO.output(16,  GPIO.HIGH)
GPIO.output(20,  GPIO.HIGH)
GPIO.output(21,  GPIO.HIGH)
temp = ''
