8 – Laboratoriya ishi
7 ta yetti segmentli indikatordan tashkil topgan 4 razryadli matritsa. Dinamik aks ettirishni amalga oshirish (Arduinoda)
Ishdan maqsad: Arduino platformasida ma’lumotlarni namoyish qilish uchun
4-bitli yetti segmentli matritsani ishlash imkoniyatini o’rganish.
Kerakli komponentlar:
• Arduino UNO platformasi;
• kompanentlarni ulash uchun maket platasi;
• 4-bitli yetti segmentli matritsa;
• qarshilik 510 Ohm - 8 dona;
• knopka;
• qarshilik 10 kOm;
• Ulovchi simlar.
Yetti segmentli ko'rsatkichlarning 4 xonali matritsasi to'rtta yetti segment displeylaridan iborat va matritsada bir vaqtning o'zida 4 ta raqamni namoyish qilish uchun mo'ljallangan, shuningdek, o'nli kasrni ko'rsatish imkoniyati mavjud. 7 segmentli displeylarda 4-bitli matritsaning diagrammasi shakl. 8.1.

8.1-rasm. 7 segmentli displeylarda 4-bitli matritsaning sxemasi
Raqamni ko'rsatish uchun siz A - G va DP pinlariga kerakli displeylarni yoqishingiz va 6, 8, 9 yoki 12 pinlariga LOW berish orqali kerakli matritsani tanlashingiz kerak. Matritsa kontaktlarini Arduino platasiga ulang va sonlarni matritsaning turli bitlariga chiqaring. Ulanish uchun bizga 12 ta Arduino pini kerak. 4-bitli matritsani Arduino platasiga ulash uchun simlar diagrammasi shakl. 8.2. Kontaktlarni ulashda 510 ohm cheklash rezistorlari ishlatiladi.

8.2-rasm. Arduino-ga 4-bitli matritsani ulash sxemasi
Matritsaning o'zboshimchalik bilan ro'yxatga olinishiga (0-9) raqamlarning ketma-ket chiqishi eskizini yozamiz. Biror qatordan tasodifiy qiymatni tanlash uchun biz random () funktsiyasidan foydalanamiz. Raqamlar [] qatori 0-9 raqamlarini ko'rsatish uchun ma'lumotlarga mos keladigan qiymatlarni saqlaydi (baytning eng muhim biti indikator segmenti A yorlig'iga, eng kami - G segmentiga to'g'ri keladi), pinlar [] qatori A - G va DP segmentlari uchun pin qiymatlarini o'z ichiga oladi array pindigits [] - matritsa bitini tanlash uchun kontaktlarning qiymatlari.
