Paper Puppets

A lab report by Michael Chan

Part A. Actuating DC motors

Link to a video of your virbation motor

Vibration Motor

Part B. Actuating Servo motors

Part 1. Connect the Servo to your breadboard

a. Which color wires correspond to power, ground and signal?

Red is the power, brown is the ground and ornage is the signal.

Part 2. Connect the Servo to your Arduino

a. Which Arduino pin should the signal line of the servo be attached to?

It should be on pin 9 per the myservo.attach line of code.

b. What aspects of the Servo code control angle or speed?

The angle is controlled by the intialization of the for loops. The 180 to 0 tells the servo to rotate from 0 to 180 degrees. The steps in the for loop indicate how fast it should change angle, in this case it is set at 1 degree.

Part C. Integrating input and output

Include a photo/movie of your raw circuit in action.

Raw Circuit

Part D. Paper puppet

a. Make a video of your proto puppet.

Paper Puppet

Part E. Make it your own

a. Make a video of your final design.

I attempted to assemble the countdown paper puppet, however i was unable to get good enough contact with the screw and paper to make the paper actually rotate around and coutndown.

    delay(15);                       // waits 15ms for the servo to reach the position
  }
  for (pos = 180; pos >= 0; pos -= 1) { // goes from 180 degrees to 0 degrees
    myservo.write(pos);              // tell servo to go to position in variable 'pos'
    delay(15);                       // waits 15ms for the servo to reach the position
