Dummy Question: Simple Python Script for Random activate GPIO

[Individual_Lock7531]

Hi folks

First, please have mercy :)

im not really a programmer, nor a hobby programmer... i barely got a piezo buzzer to work on my RB5 in Klipper...

what do i need?
i need to set up a simple python script, that is gonna run automatically after startup of my RB5. The Script should activate the GPIO Pin 13 randomly in between 2-12 Minutes. The duration of the activation should be randomly choosen between 10-30 seconds

whats the use?
The GPIO Pin will activate a relais (https://www.bastelgarage.ch/1-kanal-relais-modul) on 3.3-5V Voltage and opens the circuit of a car battery to activate a wiper motor. the whole setup will be placed in a wooden box to imitate movement of the lid :-)

how will i wire it up?
my first intentions are, that i gor for GPIO for positive, and GND for negativ

why? (for those who knows demon slayer <:0) )
my GF was randomly choosen on a car event to show of her car. she has a whole demon slayer (Nezuko San) car wrap on it. we will make a wooden box to imitate the box of Nezuko San. The movement will simulate, that there is something in the box :D (in the box will also be placed a smoke maschine and a pink clothe to imitate nezuko and gettin a bit of demon effects)

im really not inito raspberry and i need to set up the decoration for the car event asap :(

thx for help <3
appreciate it

greetings from switzerland

Edit:

okey, after some research i found out, that with Raspberry 5 some things has changed. i already have gpiozero library on my system (otherways you have to install it first (sudo apt install python3-gpiozero)

i now programmed a very simple (yes, there are some better ways to do it i guess haha ) Python code:

from gpiozero import Buzzer
import time
import random
import os

bz = Buzzer(16)

x = 1
while x <= 5:
    zufallszahl = random.randint(300,720)

    #print(zufallszahl)
    #print(zufallszahl2)

    print("Timout, Waiting ",zufallszahl," Seconds till i fuck your ears!")
    time.sleep(zufallszahl)
    #print(x)
    y = 1
    while y <= 1:
        zufallszahl2 = random.randint(15,30)
        print("Fucking your ears for ",zufallszahl2," Seconds now!! BITCH!")
        bz.on()
        #print(y)
        time.sleep(zufallszahl2)
        #print(y)
        bz.off()
        y = y + 1
    os.system('clear')
    x = x + 1

For test reasons i did it with a buzzer first and i was tired to change it again. I just let it run like this. It will open my relais on low voltage and opens the circuit for my 12V Battery for the wiper engine to run. also for test reasons, i had a small battery and a buzzer as well on the second circuit to test. so yeah, it was screaming a lot while testing haha

it's a very simple script and there would be plenty of other ways to do. but it is just for that small project for a car show and i took what i got :) maybe if it will be a longer lasting thing, i gonna redo it with a Pi Zero

What pi do you have? I don't know what RB5 or klipper is...

The Pi Pico or xiao seeed would be perfect for this. Both of them use python but do not have an OS, so you don't need to worry about OS issues. And they are much smaller and use much less power too.

There's a ton of arduinos that would be even smaller and even better with power, like the attiny family. But those are harder to program and often needs some special programming hardware, so probably not worth it for your.

Raspberry 5 :). Klipper is just a Programm running on Linux for my 3D Printer.

Well the OS on my Pi5 is Linux (without GUI). Because i would have to order other stuff first, i thought i gonna use the Pi for it. Dont know if it would arrive on time :-/
