Скачать или смотреть Control Multiple LEDs with a Button on Raspberry Pi 5 using Python

In this video, I demonstrate how to control a sequence of LEDs using a button on Raspberry Pi 5 with Python. The program toggles a running LED sequence on and off each time the button is pressed, using the gpiozero library.
🔹 Hardware Used: Raspberry Pi 5, 3 LEDs, Push Button, Resistors, Jumper Wires
🔹 Software: Python, GPIO Zero Library
🔹 Code Overview:
3 LEDs are connected to GPIO 17, 22, and 27.
A Button on GPIO 4 starts and stops the LED sequence.
The LEDs turn on one after another, with a 1-second delay in between.
Pressing the button again stops the sequence.

Code:
from gpiozero import Button, LED
from time import sleep

Initialize LEDs and button
led1, led2, led3 = LED(17), LED(22), LED(27)
switch = Button(4)
running = False # Track LED sequence state

Toggle function for the button
def toggle_running():
global running
running = not running

switch.when_pressed = toggle_running # Assign button action

LED sequence loop
while True:
if running:
for led in [led1, led2, led3]: # Cycle through LEDs
led.on()
sleep(1)
led.off()
