Laboratoriya ishi №13. Yetti segmentli bitta raqamli ko‘rsatkich. Laboratoriya ishining maqsadi

Laboratoriyaning amaliy qismi.
Modelni yig‘ish uchun bizga kerak:

• 
  Arduino Uno / Arduino Nano / Arduino Mega platasi;
  
• 
  bir xonali yetti segmentli indikator 5161as / hdsp 7503;
  
• 
  teginish tugmasi;
  
• 
  rezistorlar 220 Ohm;
  
• 
  panel;
  
• 
  papa-papa simlari.
  

Modelning Arduinoga ulanish sxemasi:

5161as / hdsp 7503 modulini smenali registrsiz ishlatish uchun indikatordagi LEDlarni yoqish uchun ko‘p sonli Arduino Uno pinlaridan foydalanish kerak bo‘ladi. Birinchi misolda, biz paneldagi turli raqamlarni ko‘rsatish uchun LEDlarni navbatma -navbat yoqamiz / miltillatamiz. Yuqoridagi rasmda bo‘lgani kabi sxemani yig‘ing va quyidagi eskizni mikrokontrollerga yuklang.


Ushbu model uchun quyidagi dastur mos keladi:
#define A 8
#define B 7
#define C 6
#define D 5
#define E 4
#define F 3
#define G 2


void setup() {
pinMode(A, OUTPUT);
pinMode(B, OUTPUT);
pinMode(C, OUTPUT);
pinMode(D, OUTPUT);
pinMode(E, OUTPUT);
pinMode(F, OUTPUT);
pinMode(G, OUTPUT);
}


void loop() {
digitalWrite(A, LOW); //bir raqami
digitalWrite(B, HIGH);
digitalWrite(C, HIGH);
digitalWrite(D, LOW);
digitalWrite(E, LOW);
digitalWrite(F, LOW);
digitalWrite(G, LOW);
delay(1000);
digitalWrite(A, HIGH); //ikki raqami
digitalWrite(B, HIGH);
digitalWrite(C, LOW);
digitalWrite(D, HIGH);
digitalWrite(E, HIGH);
digitalWrite(F, LOW);
digitalWrite(G, HIGH);
delay(1000);
digitalWrite(A, HIGH); //uch raqami
digitalWrite(B, HIGH);
digitalWrite(C, HIGH);
digitalWrite(D, HIGH);
digitalWrite(E, LOW);
digitalWrite(F, LOW);
digitalWrite(G, HIGH);
delay(1000);
}
Kod uchun tushuntirishlar: eskiz katta, shuning uchun biz o‘zimizni uchta raqam bilan chekladik. Arduino 7 segmentli indikatorda boshqa raqamlarni ko‘rsatish qiyin emas.
