Project Mission
Over the course of six months, our team set out to develop an interactive web app to allow curious pedestrians to interact with the Hub. Along with relevant information, the web app includes features for various user-interactions (i.e. ability to play music, or configuring the coloring scheme of LED lights embedded in the Hub).
We decided to include a parser to filter RSS feeds for emergencies and change the state of the Hub based on keywords in the feed.
Phase I:
