This project is using the Johnny-Five library to cycle through colors on a Tri-Color LED, dependent on a pressure sensor.

To run the code, clone the repo, cd into the directory, and run npm install. Then run node colors.js. The pressure sensor input will be logged in the terminal.

Video is below. You'll need an Arduino (set up with the Firmata protocol), a tri-color LED, and a few resistors. (I destroyed my first LED by forgetting the resistors. Oops.)
