Laboratoriya ishi №8

74HC595 suruvchi registr mikrosxemasi (Arduino oyoqchalarini tejash)
Mashg’ulotning maqsadi: Bu mashg`ulotda Arduino ni 74HC595 – chiqishlar sonini oshiruvchi mikrosxema bilan ishlashi ko’riladi.

Sxemani yig’ish uchun kerakli komponentlar:

• 
  Arduino UNO kontrolleri;
  
• 
  sxema yig’ish uchun plata;
  
• 
  yorug’lik diodi – 8 dona
  
• 
  qarshilik 510 Om – 8 dona;
  
• 
  74HC595 mikrosxema;
  
• 
  ikki uchida razyomlari bo’lgan simlar.
  

1-chizma

1-listing

int dataPin = 10;

int latchPin = 11;

int clockPin = 12;

void setup() {

pinMode(latchPin, OUTPUT);

pinMode(clockPin, OUTPUT);

pinMode(dataPin, OUTPUT);

}

void loop() {

byte byteToSend = 0;

for (int bitPos = 0; bitPos < 8; bitPos++) {

byteToSend = 0;

bitWrite(byteToSend, bitPos, HIGH);

digitalWrite(latchPin, LOW);

shiftOut(dataPin, clockPin, LSBFIRST, byteToSend);

digitalWrite(latchPin, HIGH);

delay(150);

}

byteToSend = 0;

for (int bitPos = 0; bitPos < 8; bitPos++) {

bitWrite(byteToSend, bitPos, HIGH);

digitalWrite(latchPin, LOW);

shiftOut(dataPin, clockPin, MSBFIRST, byteToSend);

digitalWrite(latchPin, HIGH);

delay(150);

}

}
Ulanish tartibi:

1. 1-chizmadagi sxema bo’yicha sxema yig`iladi.

2. 1-listingdagi sketchni Arduino platasiga yuklanadi.
