ULTRASONIK + ARDUINO + LCD

Skema Pengkabelan

Alat yang di butuhkan adalah  :

Listing Programnya  adalah seperti di bawah ini :


#include <LiquidCrystal.h>
LiquidCrystal lcd(12, 11, 10, 5, 4, 3, 2);
int backLight = 13; // pin 13 will control the backlight

int signal=40;
int vol=42;  // Untuk Mensuply tegangan 5 Volt
int gron=44;  // Untuk Mensuply Ground
int distance;
unsigned long pulseduration=0;

void setup()
{
// bagian display
pinMode(backLight, OUTPUT);
digitalWrite(backLight, HIGH); // turn backlight on. Replace 'HIGH' with'LOW' to turn it off.
lcd.begin(16,2); // columns, rows. use 16,2 for a 16x2 LCD, etc.

 // bagian ultrasonik
 pinMode(signal, OUTPUT);
 pinMode(vol,OUTPUT);
 pinMode(gron,OUTPUT);
 Serial.begin(9600);
}

void measureDistance()
{
 // set pin as output so we can send a pulse
 pinMode(signal, OUTPUT);

// set output to LOW
 digitalWrite(signal, LOW);
 digitalWrite (vol,HIGH ); // memberikan suply tegangan 5 Volt
 digitalWrite (gron,LOW ) ; // memberikan suply tegangan 0 volt(ground)
 delayMicroseconds(5);

 // Mengirim fulsa 5uS pulse out to activate Ping)))
 digitalWrite(signal, HIGH);
 delayMicroseconds(5);
 digitalWrite(signal, LOW);
 // mengganti modus ultrasonik menjadi membaca data pantulan sinyal
 pinMode(signal, INPUT);
 pulseduration=pulseIn(signal, HIGH);
}
void loop()
{
 // get the raw measurement data from Ping)))
 measureDistance();
 // divide the pulse length by half
 pulseduration=pulseduration/2;
 // now convert to centimetres. We're metric here people...
 distance = int(pulseduration/2.9);
 // Display on serial monitor
 Serial.print(" Hasil Pengukuran :  ");
 Serial.print(distance);
 Serial.println(" mm");
// Menampilkan hasil di LCD display
      lcd.setCursor(0,0);
      lcd.clear();
      lcd.print("Hasil Pengukuran");
      lcd.setCursor(1,1);
      lcd.print ("Jarak :");
      lcd.setCursor(9,1);
      lcd.print (distance);
      lcd.setCursor(14,1);
      lcd.print ("mm");
 delay(333);
}
