For this project, I created a self-celebration tool with a servo motor and a switch button. When user switches on the tool, the servo will be activated and shows the message – "Great Job!"

Servo myServo;
int servoPin = A3;
int servoPos = 0;
int buttonPin = D3;
int buttonState;


void setup() {
    
    pinMode( buttonPin , INPUT_PULLUP); // sets pin as input
    
    myServo.attach(A3);

    //Register our Particle to control the servo
    Particle.function("servo", servoControl);
    // Keep a cloud variable for the current position
    Particle.variable(  "servoPos" , &servoPos , INT );

}

void loop() {
    int buttonState = digitalRead( buttonPin );
    
    if(buttonState == LOW){
        servoControl("0");
    }else{
        servoControl("0");
    }
   

}


// function that takes an integer to set servo position
int servoControl(String command){
    // Convert
    int newPos = command.toInt();
    // Make sure it is in the right range
    // And set the position
    servoPos = constrain(newPos, 0 , 100);
    // Set the servo
    myServo.write( servoPos );
    // done
    return 1;

}

Reflection

This skills dev helped me to get familiar with using servo. One takeaway is that the servo moves rather fast, which serves the purpose of this tool. But if I need smoother movement in the future, I will probably need to write the servo position step by step with delays between the steps.
