Visualize music using Node.js, microcontroller, LEDs, Web Audio API & WebSockets

I gave a talk named "NERD DISCO" at JSConf EU 2014 and you can find it on YouTube.

Description

A local network of single-board computer (Tessel) running Node.js & providing an API to control different kind of devices: LED tower & LED wall. This network is dominated by one main computer to control the Tessel & a web app to analyze sound using the Web Audio API. The data is transfered between the browser and the main computer using WebSockets. The LEDs are called NeoPixel from Adafruit.
