Project 2 - I'll have nightmares about gears now

Image
  I have uploaded several videos about my gear testing progress to this google drive folder: https://drive.google.com/drive/folders/1VtR3xDiZZaTf3fNgudUu_1eEK-AHQPlw?usp=drive_link I learned a lot about gear ratios (how to slow down you add small gear on motor and large gear on objects), gear teething, and the extreme importance of a set screw.

Project 3 - Code

Project 3 Statement - Lumina the Ballet Bot

Image
       For Project 3 I create Lumina the Ballet Bot. This project was inspired by my mom who was a ballerina. Just like how my mom is always positive shining light into darkness, Lumina dances only when it is dark. This project is dedicated to my mom who through pushes through hard times,  continues to support me, and serves as an inspiration.      I used an Arduino micro-controller for this project.  Lumina responds to light using a photo-resistor and looks for values < 25. When it is dark, the servo motor spins Lumina, an LED light turns on, and the piezzo buzzer plays Fur Elise. I switched from Ode to Joy to Fur Elise because the original song sounded off and Fur Elise was one of my favorite songs that I used to play on the piano. A difficulty in this project was having all the components working in parallel when Arduino doesn't "support" parallel programming. After trial and error and playing around with where values are updated in the loop I was able to achieve al
