The idea came from Vincent, who wanted to do something based off of Back to the Future Part II which meant a part of the infamous jacket that could do it all: retractable sleeves.
We used two continuous rotation servo motors, a temperature sensor, 10 nF capacitor, a spark core, and the rest was coding and wiring. If the temperature sensor gets a reading above 23-degrees celsius the sleeves will roll up and not make a change until the temperature varies by more than 2 degrees.
We 3D printed the winch components, and implemented laser cut sleeve bracelets.
A Web app to was also created to override the control of the sleeves and is hosted on Azure's cloud. Communication between Azure and the Spark Core was implemented flawlessly.
The web app is found in the link above ^^, which takes in the current temperature of San Francisco.
