Outcome

Intention

The intention of this exercise is to create a material interaction with a motor, as well as to use the particle cloud to control the device.

Process

Basically I want use the sero to make a device which is a timer. This timer can represent the left time of an set event. For example, I want to use it to when I need to finish a task within 15mins. Then the timer will change the angle every 5 mins.
I use a servo to do this, also a Particle cloud function to control it.

int servoPin = A3;
Servo servo;
bool servoPositionUpdated = false;
int servoPos = 0;

void setup() {
    
    servo.attach(servoPin);
    Particle.function("position", setPosition);
}

void loop() {
    
    if (servoPositionUpdated == true){
        servo.write(servoPos);
        servoPositionUpdated = false;
    }
    
}


int setPosition (String cmd) {
    
    int input = cmd.toInt(); 
    if (input > 180) {
        return -1;
    }
    if (input < 0) {
        return -1;
    }
    int angle = map(input, 15, 0, 0, 90); // map the input value to rotaton angle
    servoPos = angle;
    servoPositionUpdated = true;
    return 1;
}
