Program Ultrasonik dengan Servo Motor menggunakan ESP32 di Wokwi

Halo semuanya! Berjumpa dengan Miniblog dari Inzaghi's Blog! Kali ini kita akan membuat Program Potentiometer dengan LED menggunakan ESP32 di Wokwi.

Sumber Tutorial : Arduinogetstarted.com

Lalu, kita akan membuat Program Ultrasonik dengan Servo Motor menggunakan ESP32 di Wokwi.

Kode :

#include <Servo.h>
// constants won't change
const int TRIG_PIN  = 4;  // Arduino pin connected to Ultrasonic Sensor's TRIG pin
const int ECHO_PIN  = 6;  // Arduino pin connected to Ultrasonic Sensor's ECHO pin
const int SERVO_PIN = 3; // Arduino pin connected to Servo Motor's pin
const int DISTANCE_THRESHOLD = 50; // centimeters
Servo servo; // create servo object to control a servo
// variables will change:
float duration_us, distance_cm;
void setup() {
  Serial.begin (9600);       // initialize serial port
  pinMode(TRIG_PIN, OUTPUT); // set arduino pin to output mode
  pinMode(ECHO_PIN, INPUT);  // set arduino pin to input mode
  servo.attach(SERVO_PIN);   // attaches the servo on pin 9 to the servo object
  servo.write(0);
}
void loop() {
  // generate 10-microsecond pulse to TRIG pin
  digitalWrite(TRIG_PIN, HIGH);
  delayMicroseconds(10);
  digitalWrite(TRIG_PIN, LOW);
  // measure duration of pulse from ECHO pin
  duration_us = pulseIn(ECHO_PIN, HIGH);
  // calculate the distance
  distance_cm = 0.017 * duration_us;
  if(distance_cm < DISTANCE_THRESHOLD)
    servo.write(90); // rotate servo motor to 90 degree
  else
    servo.write(0);  // rotate servo motor to 0 degree
  // print the value to Serial Monitor
  Serial.print("distance: ");
  Serial.print(distance_cm);
  Serial.println(" cm");
  delay(500);
}

Mohon maaf apabila ada kesalahan sedikit pun pada Kode Program ini.

Terima Kasih 😀😊😘👌👍 :)
