Is there someone that knows how to simply turn on or off a gpio pin? I don't understand why rpi have to make it so hard. I hope someone gives me an answer, ask me if you don't understand the question. I have tried for a long time to find info online and ended up on this page.

  • There are about 20 different ways in multiple languages. Try some research. Start at raspberrypi.com which has extensive documentation or read MagPi.

Here is an example of turning GPIO pin 23 on/off using the RPi.GPIO library:

import RPi.GPIO as GPIO
import time

gpioPin = 23

GPIO.setmode(GPIO.BCM)
GPIO.setwarnings(False)
GPIO.setup(gpioPin, GPIO.OUT)

while True:
    print('on')
    GPIO.output(gpioPin, GPIO.HIGH)
    time.sleep(1)
    
    print('off')
    GPIO.output(gpioPin, GPIO.LOW)
    time.sleep(1)
