An LED placed at each of the fifty state capitals updates its color every 20 minutes over the internet to reflect the current temperature in that city. The legend on the right side indicates what temperature each color corresponds to.
I was contracted by my local makerspace, NextFab, to build an Internet of Things (IoT) project that would encourage members to learn and experiment with IoT. I wanted to create something that would feel novel and exciting, yet be open ended enough to inspire variations or additions for future work. Visualizing internet weather data with LEDs was a fun and easy way to show off IoT concepts. The completed map now hangs in the front lobby at NextFab.
At the end of the project, all of the files were open sourced and made available to the public. Download the how-to guide as a PDF (1.7 MB).
