LED button doesn't work

Question

I have tried connecting a LED with a button like this (from "Adventures in RPi"), but with the far end of the button plugged at G (instead of F).

And I ran it with the following Python program (by following instructions from the said book):

import RPi.GPIO as GPIO
import time
GPIO.setmode(GPIO.BCM)
GPIO.setup(23, GPIO.OUT)
GPIO.setup(24, GPIO.IN)
while True:
    if GPIO.input(24):
        GPIO.output(23, True)
    else:
        GPIO.output(23, False)
        time.sleep(0.1)

But when I tried running the program it didn't work. To debugg it I changed the if code block to this:

    print("button")
    ##GPIO.output(23, True)

And it resulted in many prints of "button"...

• How can I fix the program (or wiring?) so that the button will turn the LED on?

Thx in advance! :)

EDIT: Here are photos of the actual wiring:

Answer 1

Try using

from gpiozero import LED, Button
from signal import sleep

Then you can do

led = LED(24)
button = Button(23)

And do

button.when_pressed = led.on
button.when_released = led.off
pause()

This makes things simpler, and it might just work.

And are you sure your wires are lined up with your button? In the real photo it's hard to tell. Maybe you can try making the resistor under the LED? I don't know if your raspberry pi breadboard only goes one way or not. Plus, you do realize that 3 wires are going into the button in your wiring right? The yellow one, the black one and the blue one. I'm talking about the wires that are connected straight-up to the raspberry pi.
