io pins of a raspberry pi

IO pins are little pins on the side of a Raspberry Pi, allowing you to send signals to other devices. they are quite easy to work with in the raspberry pi using a python script,

GPIO.setwarnings(False)
GPIO.setmode(GPIO.BCM)
GPIO.setup(fan_pin, GPIO.OUT)
GPIO.setup(smoke_pin, GPIO.OUT)

the above code can be used to set up gpio pins, and then you can use something like:

	is_on = true
	GPIO.output(fan_pin, is_on)

to turn them on.

See a more comprehensive section of code underneath, started by me and extended by Jakob.

import time
 
import RPi.GPIO as GPIO
# import vlc
 
fan_pin = 24
smoke_pin = 23
 
fan_on = False
smoke_on = False
 
GPIO.setwarnings(False)
GPIO.setmode(GPIO.BCM)
GPIO.setup(fan_pin, GPIO.OUT)
GPIO.setup(smoke_pin, GPIO.OUT)
 
state = False
 
# ...
 
if fan_now_on is not fan_on:
	fan_on = fan_now_on
	GPIO.output(fan_pin, fan_now_on)
	print(seconds, f"{fan_now_on=}")
 
if smoke_now_on is not smoke_on:
	smoke_on = smoke_now_on
	GPIO.output(smoke_pin, smoke_now_on)
	print(seconds, f"{smoke_now_on=}")
