Kursga kirish

Ushbu darsda siz Arduino-dan tugmalar, LEDlar va rezistorlar bilan birgalikda yorug'lik shousini yaratish uchun qanday foydalanishni o'rganasiz.

Tugmani bosish turli xil yoritish rejimlari o'rtasida almashinadi.

Eslatma

Agar siz Arduino loyihasi bilan birinchi marta ishlayotgan bo'lsangiz, avval asosiy materiallarni yuklab olish va ko'rib chiqishingizni tavsiya qilamiz.

Kerakli komponentlar

Ushbu loyihada bizga quyidagi komponentlar kerak bo'ladi:

KOMPONENT KIRISH | MIQDORI

Arduino UNO R4 Minima =1

USB Type-C kabeli = 1

Kabel kanal ( taxtasi) =1

Simlar = Bir nechta

1kΩ rezistor = Bir nechta

Tugma = 3

LED = Bir nechta

Simlar

Umumiy ulanishlar:

LED

LED katodini 1 kΩ rezistorga , so'ngra non platasidagi manfiy quvvat shinasiga va LED anodini Arduinodagi 2 dan 9 gacha bo'lgan oraliqlarga ulang.

Tugma

Breadboardning salbiy quvvat avtobusiga ulang.

Arduino'da 10 dan 12 gacha ulanish .

Kodni yozish

Eslatma

Ushbu kodni Arduino IDE ga nusxalashingiz mumkin .

"Yuklash " tugmasini bosishdan oldin platani (Arduino UNO R4 Minima) va to'g'ri portni tanlashni unutmang .
