Nazorat savollariga javoblar

1. 
   void - bu C, C++, Java, C#, Objective-C, D, ActionScript va PHP dasturlash tillarida tur, tur spetsifikatsiyasi va kalit so'z.
   
2. 
   Arduino-dagi pinMode o'qish yoki yozish operatsiyalarini bajarish uchun pinning ishlash rejimini o'rnatishga yordam beradi. Odatda, bu funksiya setup() usuli ichida ishlatiladi va dastur ishga tushganda bir marta bajariladi. Arduino kirish va chiqish rejimini noto'g'ri sozlash loyiha va plataning ishlashiga ta'sir qilishi mumkin.
   
3. 
   Funktsiya ish kuchlanishini (ko'p hollarda 5V) pinlarga qo'llash yoki olib tashlash orqali ulangan Arduino uskunasini boshqarishga imkon beradi. Aslini olganda, digitalWrite Arduino-ni bizning vazifalarimizga qarab portlarida kuchlanishni yoqadigan yoki o'chiradigan katta aqlli rozetkaga aylantiradi.
   
4. 
   Arduino kechikishi eng oddiy buyruq bo'lib, ko'pincha yangi boshlanuvchilar tomonidan qo'llaniladi. Aslida, bu qavslarda ko'rsatilgan millisekundlar soni uchun dasturni to'xtatib turadigan kechikishdir. (Bir soniyada 1000 millisekund bor.) Maksimal qiymat 4294967295 ms bo'lishi mumkin, bu taxminan 50 kunga teng.
   

XULOSA

Men bu laboratoriya ishini bajarib ARDUINO, led lampochka, resistor haqida bir qancha bilimlarga ega bo’ldim. Arduino yordamida yorug’lik diodini o’chirib yoqishni o’rgandim va bir qancha nazariy savollarga javob topdim.
