3.1 Bir razryadli yetti segmetli indikator. Arduino MK orqali raqamlarni indikatorga chiqarish.

Bir razryadli yetti segmentli indikator. Arduino MK orqali raqamlarni indikatorga chiqarish
Ishdan maqsad: Arduino platformasida raqamlarni namoyish qilish uchun
7-segmentli displeyni ishlash imkoniyatini o’rganish.
Kerakli komponentlar:
• Arduino UNO platformasi;
• kompanentlarni ulash uchun taxta;
• bir xonali etti segmentli displey;
• 510 Ohm qarshilik - 7 dona;
• Ulovchi simlar.
Yetti segmentli displey ma'lum bir tartibda joylashtirilgan va tizimli ravishda birlashtirilgan displeylar guruhidir. Displey kontaktlari a dan g gacha bo'lgan belgilar bilan belgilanadi (va qo'shimcha ravishda dp - o'nli kasrni ko'rsatish uchun) va indikator ulanish turini aniqlaydigan bitta umumiy terminal (umumiy anodli OA yoki umumiy katod OK). Bir vaqtning o'zida bir nechta Displeyni yoqib, indikatorda raqamli belgilar hosil qilish mumkin. Bir xonali etti segmentli indikatorning diagrammasi shakl. 7.1.
