Program Ultrasonik dengan LED menggunakan ESP32 di Wokwi

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

Sumber Tutorial : ESP32io.com

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

Kode :

#define TRIG_PIN  18 // ESP32 pin connected to Ultrasonic Sensor's TRIG pin
#define ECHO_PIN  19 // ESP32 pin connected to Ultrasonic Sensor's ECHO pin
#define LED_PIN   21 // ESP32 pin connected to LED's pin
#define DISTANCE_THRESHOLD 50 // centimeters
// variables will change:
float duration_us, distance_cm;
void setup() {
  Serial.begin (9600);       // initialize serial port
  pinMode(TRIG_PIN, OUTPUT); // set ESP32 pin to output mode
  pinMode(ECHO_PIN, INPUT);  // set ESP32 pin to input mode
  pinMode(LED_PIN, OUTPUT);  // set ESP32 pin to output mode
}
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)
    digitalWrite(LED_PIN, HIGH); // turn on LED

  
  else
    digitalWrite(LED_PIN, LOW);  // turn off LED
  // 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 😀😊😘👌👍 :)
