Python
The python function that orchestrates the weather reading translation and servo movements

Argon code

Java
The code deployed on argon
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("MoveTo", moveServoTO);  

    myservo.attach(D2);   // 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
    
     Particle.publish("Setup Module", "STarting", PRIVATE);
}


int moveServoTO(String command)
{   
    myservo.attach(D2); 
    
    int newPos = command.toInt();
    myservo.write(newPos);       
       
    Particle.publish("**Servo Moving TO **"+command, "position:"+ command, PRIVATE);
        
        
    delay(3000);
        
    myservo.detach();

        
        return 1;               // return a status of "1"
    
  //  return 0;
}

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