This is the server part of my NodeKeyboard app, a project that joins Raspberry Pi, Makey makey and Node in one and awesome project!
This is a part of a full project so you will need to download the other parts in:
NodeKeyboardAPP, the node app sockets and makeymakey for the win!
NodeKeyboardWEB, the webapp we use to listen to sounds and add questions
Then you must change the database connection (in config.js) and maybe the port (in the same file).
You only need to execute the app.js; the server will create the socket server and connect with the database. <
