Just got back from a family emergency and didn't have much time to build something interesting this week, mainly because I missed the input/output devices weeks. With only my button and LED board to work with, I learned a bit more about node.js and the Google Maps API, creating a simple zoom button. Holding down the button zooms in on the map. Double-clicking-and-holding the button zooms out. The map will be one of the main visualization modes in my final project.
