Nurafshon-2024
2-amaliy topshiriq.
Topshiriqlar:
1. Potensiometrdan foydalangan holda arduino orqali yorug‘lik diodining yorug‘lik darajasini o‘zgartirish va ularning sonini o‘zgartirish.
2. RGB-yorug‘lik diodi. Impuls kengligining modulyatsiyasi.
3. Bir va to‘rt razryadli yetti segmetli indikatorlardan foydalanish va raqamlarni indikatorga chiqarish.
4. Tinkercad platformasidan foydalangan holda topshiriqlarni simulatsiyasi (prototip)ni ishlab chiqish.
5. Bajarilgan amaliy ishning dasturiy ta’minotini ishlab chiqish va topshiriqni o‘z vaqtida himoya qilish.
