Week 2

During the second week, we made more concrete decisions on the mechanisms of the animatronic and drew another sketch of the alien with more details. We also started to practice coding on the Arduino by learning how to turn a LED on and off.
Sketch:

Programming:
Arduino
Electrical board:
Arduino
Mechanisms:
  1. 90 degree turn, propping alien from horizontal position to vertical position
    1. Stepper motor: programmed to QUICKLY turn by 90 degrees
    2. Instead of using a piston which would be more complicated, we could set a stepper motor to a higher speed to get that quick jumpscare effect. Youtube video below is an example of a high speed stepper.

  2. Swaying motion (back and forth)
    1. Stepper motor: connect to wheel. Connect stiff rod to off-center position on wheel. Connect wheel to alien, similar to train wheel motion
    2. https://youtu.be/78Rl6BWoQp0?t=47
  3. Spinning head 180 degrees both ways
    1. Stepper motor: located internally. Top portion of alien will not be attached to bottom portion
  4. Glowing eyes
    1. Red leds
  5. Screeching alien audio
    1. Audio set

Week 10

Plans: Assemble audio, motor, and servos all to one bread board and arduino uno drill holes for audio to play through adjust latex sizing for alien add stopper to alien figure out winch system Results: Assembled all parts to one arduino uno, but had to scrap winch idea The alien will only pop up, but will not go back into the box again
