4)Programma kodini arduinoga yuklash uchun quyidagi rasmdagi

instrumentga sichqoncha ko’rsatkichini olib borib bosing.
Tizim kompilyatori dasturni tekshirib xatosiz bo’lsa kontrollerga yuklaydi va programma ishga tushadi. Agar dastur kodida xatolik bo’lsa kompilyator bu xatolikni qizil rang bilan yoritib ko’rsatadi. Xatolikni tuzatib dasturni qayta yuklang.

Nazorat savollari.

1. 
   7 segmentli displey ishlashi qanday?
   
2. 
   Bunday displeyning yana nechta segmentligini uchratish mumkin?
   
3. 
   Segmentlarni yoritishni boshqarish uchun qanday kodlardan foydalaniladi?
   
4. 
   Bunday displeylar bizga qayerlarda kerak bo’ladi deb o’ylaysiz va nega?
   
5. 
   Laboratoriya ishining asosiy vazifasini tushuntiring?

Javoblar.

1. 
   7 segmentli displeyni ishlash jarayoni haqida gapriadigan bo’lsak,avvalo segment yani bo’lak yoki qism degan ma’nolarni anglatgani uchun qurilmamiz 7 ta bo’lakdan iborat ekanligi kelib chiqadi va ularni ishlashi har bir segmentlarni ishlashi bilan bog’liq ya’ni 1 raqamini hosil qilishimiz uchun ikkita segment yonishi qolganlari o’chiq turishi kerak bo’ladi.
   
2. 
   Asosan ishlatiladigan displaylar 7,14 va 16 talik segmentlardir.
   
3. 
   Segmentlarni ketma ket yoqishni boshqarish uchun for()siklidan,digitalWrite()funksiyasidan,pinMode()funksiyasidan va delay()funksiyasidan foydalanamiz.
   
4. 
   Bunday displaylar bizga asosan raqamlarni hosil qilish uchun ishlatiladi va uni oddiy kalkulyator erkranida ko’rishimiz mumkin.
   
5. 
   Labaratoriya ishini asosiy vazifasi segment display bilan yaqindan
   

6. 
   tanishish uni ishlatib korish,unga qanday kodlar yozilishini tushinishdan iborat deb o’ylayman.
   

Xulosa.
Xulosa qilib aytishimiz mumkinki bu labaratoriya ishini bajarish davomida avvalo segment nima degan savolga javob topdim.Hamda bu rivojlanayotgan aXborot texnalogiyalari davrida displeylar yaratishda mana shu segmentdan foydalanar ekan.Oddiygina kalikulyator ham mana shu segmentdan foydalanib ishlaydi
