NEATLIGHTS

PubSub-based controller for controlling strands of addressable LED lights connected to a Raspberry Pi.

The Gist of It

In the config/config.py file, set up appropriate info for the redis pubsub instance you want to listen on. Posting a json blob/python dictionary on the specified channel will result in the listening thread parsing the message, and configuring the LED strand as specified. Examples can be found in config/blink_patterns.py.

When passing colors into the message, use the CSS3 color names: ['black', 'red', 'cornflowerblue', 'paleturquoise'].
The max brightness value is 255, and the min (lights off) is 0.
To make the strands to fancy things, you will need to write your own methods. Plenty of examples of can be found in helpers/NeatLights.py, and in order to have the method executed, you will need to modify Main.py with the name of the method.

Example Message

{
    'style_name': 'Diamonds',
    'method_name': 'party',
    'css3_colors': [
        'red', 'yellow', 'blue',
        'orange', 'purple', 'green',
        'teal', 'fuchsia', 'white'
    ],
    'brightness': 100,  # 255 max - SEE NOTE BELOW
    'led_count': 480,  # total number of LEDs being operated
    'speed': 0.01,  # speed at which lights change
    'offset': 1,  # number of LEDs to jump per tick
    'reverse_after': 500,
    'iterations': 1,
    'direction': 2,
    'cleanup': 1,
    'senselight': False  # can make use of an ambient light sensor to adjust bightness of lights based on the brightness of the room
}

NOTE: The Pi alone can power about 50 at max brightness, but any more will cause it to lock up due to lack of available energy. I added a 5v, 8Amp power supply to my lights to be able to power about 700 lights at 100 brightness.

Sorry, I this is kinda lazy. I'll try to make a proper diagram later.
