Nick Holliman posted a screenshot of Mathematica displaying the latest CheerLights color.
The Mathematica code uses the HTTPRequest function to get data from the ThingSpeak API, parse for the color, and set the color of a shape. Nick posted the Mathematica code on GitHub for anyone to try out.
I love how people find a way to use the CheerLights project and integrate it with what they have. We have seen Commodore 64 programs to buildings showing off the CheerLights color. CheerLights is also a great way to learn how to get data from an IoT API and do something with it. Once you know how to do CheerLights, you can build other cool things.
