Arduino Sample Code:

# define ECHOPIN 2 // Pin to receive echo pulse
# define TRIGPIN 3 // Pin to send trigger pulse

void setup() {
    Serial.begin(9600);
    pinMode(ECHOPIN, INPUT);
    pinMode(TRIGPIN, OUTPUT);
    digitalWrite(ECHOPIN, HIGH);
}

void loop() {
    digitalWrite(TRIGPIN, LOW); // Set the trigger pin to low for 2uS
    delayMicroseconds(2);
    digitalWrite(TRIGPIN, HIGH); // Send a 10uS high to trigger ranging
    delayMicroseconds(10);
    digitalWrite(TRIGPIN, LOW); // Send pin low again
    int distance = pulseIn(ECHOPIN, HIGH, 26000); // Read in times pulse
    distance = distance / 58;
    Serial.print(distance);
    Serial.println("   cm");
    delay(50); // Wait 50mS before next ranging
}
