Chroma lights is a frame work for running annimations for led lights over OSC.

Install virtualenv (skip if you have it already).

sudo easy_install virtualenv

Move on to running to get the environment activated and dependencies checked.

###Windows users Scroll down to see instructions since there are a buttload.

There is a simple emulator provided that will start automatically when run.py is executed if it's not running already. In your chrome-scripts directory, run the activate script. If this is your first time running it, give it a bit to fetch dependencies and setup the environment:

source activate

To run an animation:

./run.py [animation name]

If you're on zsh, tab completion should work too. If there isn't a server or emulator started, it will start the emulator for you automatically.

To contribute add a new folder in the animation directory. This folder should be have a unique name for the animation. The folder must contain the following two files:

main.py:

import sys
from oscapi import ColorsOut
...

manifest.json:

{
	"name":"Random Colors",
	"description":"Random colors on 3 second intervals",
	"creator":"RJ and Reed"
}

Each light recieves an input that is a tuple (r,g,b) where each of r, g, b can be 0-1023.

Construct an array of tuples and send them to the OSC server with

pix = [(1023.0,0.0,0.0)]*24
out = ColorsOut()
out.write(pix)

To add simple effects, such as automatic fade-in and fade-out of pixels, use the animations library in place of ColorsOut

from animations import FadeAnimation
pix = [(1023.0,0.0,0.0)]*24
out = FadeAnimation()
out.FADEINRATE = 2.0 #optional
out.FADEOUTRATE = 8.0 #optional, makes things 'trail off'
out.start()
out.write(pix)

Chroma is bright, and can easily be the predominant lighting in the room. Fast blinking of the lights can be intense, so be considerate.

• Avoid instantaneous changes in both intensity and color
• Use the provided animation framework to transition between colors

python setup.py install

pip install virtualenv

virtualenv env

env\Scripts\activate

pip install -r dependencies.txt

python run.py random

Note: be sure (env) is displayed at the beginning of every command line when running scripts, or else it will not work!
