Code

Ultrasonic Code

C/C++
The following code exemplifies the initiation of the ultrasonic sensor detecting if an object is less than or greater than 60 cm corresponding with a buzzer and LED light, simultaneously.
int trigPin = D4;
int echoPin = D5;


void setup() {
    pinMode(trigPin, OUTPUT);
    pinMode(echoPin, INPUT);
}

void loop() {
   
    long distance;
    digitalWrite(trigPin, LOW);
    delayMicroseconds(2);
    digitalWrite(trigPin, HIGH);
    delayMicroseconds(10);
    digitalWrite(trigPin, LOW);
    distance = pulseIn(echoPin, HIGH);
    
   
    if (distance > 50) {
        Particle.publish("Ultrasonic", "Breach");
    } else {
        Particle.publish("Ultrasonic", "Clear");
    }
   
}

Buzzer Code

C/C++
The following code exemplifies the enactment of the buzzer when the distance from the ultrasonic sensor is fulfilled.
void setup() {
    pinMode(D6,OUTPUT);
    Particle.subscribe("Ultrasonic", buzzit, MY_DEVICES);
}
void loop() {

}

void buzzit(const char *event, const char *data) {
   
    if (strcmp(data, "Breach") == 0) {
        tone(D6,500,3000);
    } else if (strcmp(data, "Clear") == 0) {
        tone(D6,0,0);
    }
   
}

LED Code

C/C++
The following code simultaneously enacts on the LED & buzzer when the distance is fulfilled by the ultrasonic sensor.
int led1 = D5;
int led2 =D4;
void setup() {

  pinMode(led1, OUTPUT);
  pinMode(led2, OUTPUT);
  Particle.subscribe("Ultrasonic", light, MY_DEVICES);

}

void loop() {

}

void light(const char *event, const char *data) {
 
   
    if (strcmp(data, "Breach") == 0) {
        digitalWrite(led1, HIGH);

        digitalWrite(led2, LOW);
    } else if (strcmp(data, "Clear") == 0) {
        digitalWrite(led2, HIGH);
    }
}
