JohnnySocket

Powering museum exhibits over the internet with JohnnyFive, Node.js, Socket.io, and Unreal Development Kit.

Mashing Socket.io & JohnnyFive, using TCP with UDK to hit JohnnyFive.

Overview

This project demonstrates the ability to control an arduino unit with a webpage and with TCP Messages from UDK:

Web page --------\ 
                  |
                  |--> HTTP server / TCP Server ---> TCP Client / JohnnyFive Arduino controller ---> Arduino
                  |
UDK interface ---/ 

Components

There are five components to this project:

1. Arduino
2. Node program running Johnny-Five & and a TCP client
3. Node server serving static files via HTTP, running Socket.io, and a TCP server
4. Static webpage which uses Socket.io to connect to the server.
5. A UDK interface which sends TCP commands to the server.

Getting started

1. Connect your arduino via USB & load the Firmata sketch. See Johnny-Five repo for instructions.
2. Run node server.js on the remote host which will also serve the web page.
3. Set the IP in arduino.js to the IP of your remote host: e.g. host:'66.172.10.186'
4. Run node arduino.js locally on the computer which is connected to the arduino.
5. You'll see the arduino's LED start to blink in response to the remote server. Eventually this will be controlled through a webpage.

Module dependencies
