I have updated the google drive link with the Nov 13 progress: https://drive.google.com/drive/folders/1TMbDc6vOqMedWY2nbB08juKllXF6hH5Q?usp=sharing Blogger is having a hard time supporting my videos :( I created code to combine the components together and have them all work according to the photo-resistor values (whether its dark or light). The most challenging part was integrating the piezzo and the servo motor. It was hard to get it moving with the music loop.  

This past week Nov 8-13, I had the opportunity to attend the TMU Design Invitational hosted by Universal in Orlando, FL with my project team TPEG (Theme Park Engineering Group). At the competition I was challenged to design solutions to three different challenges in a time pressured environment, while I had the opportunity to network with Universal jurors, learn more about ride technologies, and connect with students from other universities. As Alyssa mentioned during her presentation, the themed entertainment industry is an engaging application of robotics and technology.  

Check out this google drive to see my progress: https://drive.google.com/drive/folders/1TMbDc6vOqMedWY2nbB08juKllXF6hH5Q I have each of the components working: photo-resistor reacting to light, LED indicator turning on properly, and servo moving to multiple piezzo buzzer songs. I have code for Ode to Joy and the Imperial March. I also finished model work on the ballerina. Videos of the components working are in the drive link above.  

This project was inspired by my mom who was a ballerina growing up. My mom is one of my biggest supporters and brings light to the dark. Therefore, I will be creating a ballerina that starts dancing and lights up an LED when it senses the dark using a photoresistor.  

  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.
