Ultrazvukový senzor BEZ použitia špeciálnej knižnice
 
To use the HC-SR04 ultrasonic sensor with Arduino without libraries, send a 10µs HIGH pulse to the Trig pin, then measure the resulting Echo pin pulse duration using pulseIn(). Calculate distance in cm by dividing duration by 58.2 or \(0.0343\div 2\). 
 
Wiring: 
  VCC: 5V
  GND: GND
Trig: Digital Pin 9 (or any digital I/O)
Echo: Digital Pin 10 (or any digital I/O) 
 
 
Code Example:
 
<source lang="arduino" style="background: #9dd1e1;">
 
const int trigPin = 9;
const int echoPin = 10;
 
 
/* Arduino code  */
 
 
void setup() {
  pinMode(trigPin, OUTPUT);
  pinMode(echoPin, INPUT);
  Serial.begin(9600);
}
 
void loop() {
  // Clear trigPin
  digitalWrite(trigPin, LOW);
  delayMicroseconds(2);
 
  // Sets the trigPin on HIGH state for 10 micro seconds
  digitalWrite(trigPin, HIGH);
  delayMicroseconds(10);
  digitalWrite(trigPin, LOW);
 
  // Reads the echoPin, returns sound wave travel time in microseconds
  long duration = pulseIn(echoPin, HIGH);
 
  // Calculating the distance (speed of sound is ~343m/s or 0.0343 cm/us)
  float distanceCm = duration * 0.0343 / 2;
 
  // Print to Serial Monitor
  Serial.print("Distance: ");
  Serial.print(distanceCm);
  Serial.println(" cm");
 
  delay(100); // Small delay to avoid interference
}

Key Principles: 
* Trigger Pulse: A 10-microsecond high pulse is required to initiate the sensor's 8-cycle ultrasonic burst,
* Echo Pulse: The echo pin goes high for the same amount of time it takes for the sound to travel to the object and back,
* Calculation: \(\text{Distance}=\frac{\text{Duration}\times \text{Speed\ of\ Sound}}{2}\).
* Range: The sensor measures distances from 2cm up to 400cm
