I first made the circuit by following the diagram of how to connect the servo. The servo has 3 wire to connect.

// This #include statement was automatically added by the Particle IDE.
#include <Adafruit_PWMServoDriver.h>

int servoPin = A3;
Servo myServo;
int servoPos = 0;

void setup() {
     myServo.attach( A3 );
     Particle.function("servo", servoControl);
     
      // Keep a cloud variable for the current position
  Particle.variable(  "servoPos" , &servoPos , INT );


}

void loop() {

}

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 , 180);

   // Set the servo
   myServo.write( servoPos );

   // done
   return 1;
}

I had to connect it is VUSB instead of 3V3 because the servo needed more power to work. Here is the video below of the servo connected to a particle function!

To give this servo movement meaning, I took inspiration from Google's Paper Signals project and wanted to recreate an object that signifies whether a stock has gone up or down. This would be helpful if a trader is waiting on when to buy a stock. If they see that it keeps going down in value they may get ready to buy.

I had a foam core box made for a different project and decided to reuse it to give the servo form. This is a very low fidelity prototype. See the video below!!

Reflection

I enjoyed doing this exercise. I really like the meaning behind Google's Paper Signals. It is a very nice way to give tangible form to information. I'd love to take more classes where I do more work with servos and motors in general.

The goal of this project is to set up a servo and give it a physical form to conduct an action. Inspiration comes from Google Paper Signals.
