4. Upload the following code to the Arduino:

   // Controlling a servo position using a potentiometer (variable resistor) 
   // by Michal Rinott <http://people.interaction-ivrea.it/m.rinott> 
   
   #include <Servo.h> 
    
   Servo myservo;  // create servo object to control a servo 
    
   int potpin = 0;  // analog pin used to connect the potentiometer
   int val;    // variable to read the value from the analog pin 
    
   void setup() { 
     myservo.attach(3);  // attaches the servo on pin 9 to the servo object 
   } 
    
   void loop() { 
     val = analogRead(potpin);            // reads the value of the potentiometer (value between 0 and 1023) 
     val = map(val, 0, 1023, 0, 179);     // scale it to use it with the servo (value between 0 and 180) 
     myservo.write(val);                  // sets the servo position according to the scaled value 
     delay(15);                           // waits for the servo to get there 
   }

5. Connect the paper automaton to your servo and use the potentiometer to control it.
   
   

   ---

6. Use a digital caliper to measure your components. Write down the dimensions.
   
   

   ---

7. Redesign the automaton so that you can 3D print it. Make sketches. See Examples

8. Using the application of your choice model your automaton.
