Poor Man's HUE Smart Light Bulb Demo

with Arduino, Common Cathode RGB LED, Johnny-Five, and PubNub

The tutorial is available on Tuts+.

The Tuts+ tutorial was written with v1 code, so some code snippets in the tutorial do not match in the latest code in this repo. See the changes below.

Changes in v2

• Instead of sending each color value like {color:red, brightness: 123}, now all color values is sent as one object at a time, as {r: 123, g: 98, b: 0}
• Added subscribe() in the front-end code to reset the UI slider position every time other subscribers make changes
• Added history() in the front-end code to initialize the UI slider's initial state by reading the very last values from history
• Added history() in the node.js code to initialize the LED color state at the initial load
