Code

Bell Servo Motor Control

C/C++
This code will be used along with IFTTT to be able to ring the bell at a certain time
Servo myservo;  // create servo object to control a servo
                // a maximum of eight servo objects can be created

int pos = 0;    // variable to store the servo position

void setup()
{
    Particle.function("bell", bell);  // create a function called "bell" that
                                      // can be called from the cloud
                                      // connect it to the bell function below

    myservo.attach(D0);   // attach the servo on the D0 pin to the servo object
    myservo.write(25);    // test the servo by moving it to 25°
    pinMode(D7, OUTPUT);  // set D7 as an output so we can flash the onboard LED
}

int bell(String command)   // when "bell" is called from the cloud, it will
{                          // be accompanied by a string.
    
    if(command == "alarm")     // if the string is "alarm",
    {                               
        for (int i = 0; i < 30; i++) // ring the bell 3 times.
        {
            myservo.write(0);       // move servo to 0° - ding!
            digitalWrite(D7, HIGH); // flash the LED
            delay(100);             // wait 100 ms
            myservo.write(25);      // move servo to 25°
            digitalWrite(D7, LOW);  // turn off LED
            delay(200);            // wait 1 second between bells
            
            Particle.publish("Motor", "Lights on", PUBLIC);
        }
        return 2;                   // return a status of "2"
    }
    
}


void loop()
{
  // empty because we call the gong function via the cloud
}

Light Switch Subscription Code

C/C++
This code subscribes to the Bell Servo Motor Control Code from the cloud and activates a servo motor that turns the lights on
Servo myservo;  // create servo object to control a servo
                // a maximum of eight servo objects can be created

void setup()
{
  myservo.attach(D1);  // attaches the servo on the D1 pin to the servo object
  // Only supported on pins that have PWM
myservo.write(35); // starts motor at 35 degrees
}

void loop()
{
Particle.subscribe("Motor", LightsOn, "46002b000851363136363935");
  // Subscribe will listen for the event Motor and, when it finds it, will run the function LightsOn
  delay(1000); // delays the motion 1 sec after subscribing to "Motor" event
}

void LightsOn(const char *event, const char *data)
{
  /* Particle.subscribe handlers are void functions, which means they don't return anything.
  They take two variables-- the name of your event, and any data that goes along with your event. */
  
  
   if (strcmp(data,"Lights on")==0) { // if the data from "Motor" reads "Lights on" than the servo will rotate
    myservo.write(180);              // the servo arm will rotate 180 degrees
    delay(1000);                     // this makes a 1 second delay before the arm returns.
    myservo.write(35);              // arm returns to 35 degrees (starting point)
  }
 
}
