Amaliyot

Ex1) Uchta LEDni ulash va ularni birin-ketin yoqishni mashq qiling

* O'zingiz xohlagan pinga

Amaliyot

Ex2) Kalit va LED ulanishi misoli

H/W

- LED element + ga ulangan pin 36 (GPIO 16).

- LED va pin 20 (GND) o'rtasida 220 Ō rezistorni ulang

- Pin 20 qarshilik GND

- almashtirish

Dasturiy ta'minot

RPi.GPIO ni GPIO sifatida import qiling

import vaqti

GPIO.setmode (GPIO.BCM )

GPIO.setup (16,GPIO.OUT )

GPIO.setup (20,GPIO.IN )

esa 1:

agar GPIO.input (20)==1:

GPIO.output (16,1 )

boshqa:

GPIO.output (16,0)

Dasturiy ta'minot uchun eslatmalar

While dasturidan foydalanganda u cheksiz tsiklga aylanishi mumkin.

Bunday holda, cheksiz tsikldan chiqib ketish uchun break dan foydalaning yoki

Yana davom ettirish uchun davom etish tugmasidan ham foydalanishingiz mumkin.

Amaliy amaliyot _

- 3 ta kalit va 3 ta LEDni ulang.

- Kalitni LED bilan 1:1 nisbatda moslang.

- Har bir kalit bosilganda, tegishli LED yonadi, o'chadi

Sizga katta rahmat.
