Bahasa program yang digunakan :
#include <LiquidCrystal.h>
#define trigPin 5
#define echoPin 13
LiquidCrystal lcd(12, 11, 10, 9, 8, 7);
void setup() {
pinMode(trigPin, OUTPUT);
pinMode(echoPin, INPUT);
}
void loop() {
float duration, distance;
digitalWrite(trigPin, LOW);
delayMicroseconds(2);
digitalWrite(trigPin, HIGH);
delayMicroseconds(10);
digitalWrite(trigPin, LOW);
duration = pulseIn(echoPin, HIGH);
distance = (duration / 2) * 0.0344;
if (distance >= 400 || distance <= 2){
lcd.print("Out of range");
delay(500);
}
else {
lcd.print(distance);
lcd.print(" cm");
delay(500);
}
delay(500);
lcd.clear();
}
