exemplo de código

// C++ code

//

#include <Servo.h>

int distancia = 0;

long readUltrasonicDistance(int triggerPin, int echoPin)

{

  pinMode(triggerPin, OUTPUT);  // Clear the trigger

  digitalWrite(triggerPin, LOW);

  delayMicroseconds(2);

  // Sets the trigger pin to HIGH state for 10 microseconds

  digitalWrite(triggerPin, HIGH);

  delayMicroseconds(10);

  digitalWrite(triggerPin, LOW);

  pinMode(echoPin, INPUT);

  // Reads the echo pin, and returns the sound wave travel time in microseconds

  return pulseIn(echoPin, HIGH);

}

Servo servo_8;

void setup()

{

  servo_8.attach(8, 500, 2500);

}

void loop()

{

  distancia = 0.01723 * readUltrasonicDistance(7, 6);

  if (distancia <= 10) {

    servo_8.write(90);

    delay(5000); // Wait for 5000 millisecond(s)

    servo_8.write(0);

  }
