The best way to execute this code is using a callback function. This is a function that is attached to a specific GPIO pin and run whenever that edge is detected. Let’s try one:

import RPi.GPIO as GPIO

GPIO.setmode(GPIO.BCM)

GPIO.setup(23, GPIO.IN, pull_up_down = GPIO.PUD_DOWN)

GPIO.setup(24, GPIO.IN, pull_up_down = GPIO.PUD_UP)

def printFunction(channel):

    print(“Button 1 pressed!”)

    print(“Note how the bouncetime affects the button press”)

GPIO.add_event_detect(23, GPIO.RISING, callback=printFunction, bouncetime=300)

while True:

    GPIO.wait_for_edge(24, GPIO.FALLING)

    print(“Button 2 Pressed”)

    GPIO.wait_for_edge(24, GPIO.RISING)

    print(“Button 2 Released”)

GPIO.cleanup()
