In a previous Devoxx France conference, Clever-Cloud had a booth where they showed how to use their platform with a small chip that controlled a LED strip, all that communicating through a websocket making the interface with the backend hosted on Clever-Cloud. This project is on Github : https://github.com/CleverCloud/wemos-statsd-example. The cool part is that the LED strip and the chip were distributed as goodies :) I recently found this LED strip in a box, and I wanted to play with it.
