Pezonurlatgichni boshqarish: tonni o‘zgartirish, davomiligini o‘zgartirish
Ishdan maqsad: arduino muhutida dasturini tuzish va pezonurlatgichni boshqarishni o’rganish, proteusda sxemalarini yi’g’ib ishga tushurish.

1-rasm. Arduino muhida dastur yozilgan holati.

2-rasm. Proteus muhutida bizga kerakli bo’lgan barcha elemtlarni yig’ib olamiz

Proteusda barcha elementlarni yi’g’ib bir biriga ulaganimizdan so’ng arduinoda
yozgan dastur kodimizning hex. fileni ko’rsatishimiz kerak bo’ladi.

3-rasm. Arduinoda yozgan dastur kodimizning he. Fileni ko’rsatish

4-rasm. Protes muhitida dasturimizni ishga tusgan holati.

Dastur kodi:
const int echoPin = 2; // Ultrasonik sensorning echo pinasi

const int pingPin = 3; // Ultrasonik sensorning trigger pinasi

void setup()

{
Serial.begin(9600); // Serial aloqani boshlash
pinMode(pingPin, OUTPUT); // chiqish pimi 3 ni ishga tushirish
pinMode(echoPin, INPUT); // kirish pimi 2 ni boshlash
}
void loop()
{
long duration, inches, cm;

digitalWrite(pingPin, LOW); delayMicroseconds(2);

digitalWrite(pingPin, HIGH); delayMicroseconds(10);
digitalWrite(pingPin, LOW);

duration = pulseIn(echoPin, HIGH); // pulsin funktsiyasi yordamida umumiy vaqtni aniqlash

inches = microsecondsToInches(duration); // bog'lanish usuli cm = microsecondsToCentimeters(duration); // bog'lanish usuli

Serial.print("in, ");

Serial.print(cm);
Serial.print("cm");
Serial.println();
delay(100);}
long microsecondsToInches(long microseconds) // mikrosektsiyani dyuymgacha yashirish usuli
{
return microseconds / 74 / 2;
}
long microsecondsToCentimeters(long microseconds) // mikrosektsiyani santimetrgacha yashirish usuli

{
return microseconds / 29 / 2;
