Rdio Visualizer
===============
Part of a hackday project for Rdio. Takes raw data from the Rdio client and displays the real-time frequency data (like an equalizer) on a NeoPixel grid. See https://t.co/I04zMx2sqV to see everything in action.
This repo represents about 2/3 of the project. The remaining parts are Rdio specific, so they aren't shared here.
In short, there are three parts to the system: the client, the server, and the Arduino firmware.
The client code written for this project is specific to Rdio, but the output is pretty generic and could come from anywhere. The only thing the client needs to do is call the server with properly formatted FFT data. For our specific hackday, we used the [Meyda](https://github.com/hughrawlinson/meyda) framework, and used the "powerSpectrum" feature.
The server consists of a single HTTP endpoint, ```/```, which, when POSTed to, accepts url encoded data with a single parameter, 'powerSpectrum`, which is a JSON.stringified array of FFT raw data. The window size needs to be a power of two, ideally. The server takes this data and converts it to RGB raw data.
The firmware takes in serial data from the server and displays it on a NeoPixel grid. It has only been tested on https://www.adafruit.com/products/1430, but hypothetically should work on anything if you tweak the parameters properly.
See [index.js](https://github.com/bryan-m-hughes/rdio-visualizer/blob/master/server/index.js) for details and customization.
Note: this is a hackday project, and so the code is not well commented, abstracted, etc. Make of it what you will :).
