Untuk membaca sensor jarak kita butuh sensor ultrasonic dan ardino uno
Alat-alat yang di butuhkan :
Arduino Uno
Sensor Jarak/HCSR04
Kabel Jumper
Wiring :
HCSR04 :
VCC > 5V (Arduino Uno)
Trigger Pin > Pin 9 (Arduino Uno)
Echo Pin > Pin 10 (Arduino Uno)
GND > GND (Arduino Uno)
Codingan :
const int trigPin = 9;
const int echoPin = 10;
long duration;
int distance;
void setup() {
// put your setup code here, to run once:
pinMode(trigPin, OUTPUT);
pinMode(echoPin, INPUT);
Serial.begin(9600);
}
void loop() {
// put your main code here, to run repeatedly:
digitalWrite(trigPin, LOW);
delayMicroseconds(2);
digitalWrite(trigPin, HIGH);
delayMicroseconds(10);
digitalWrite(trigPin, LOW);
duration = pulseIn(echoPin, HIGH);
distance = duration*0.034/2;
Serial.print("Distance: ");
Serial.print(distance);
Serial.println(" CM ");
}
Selamat Mencoba..!!
