PyLEDServer

A Python server running on a Raspberry Pi used for controlling a WS2811 LED strip.

Installation

Requirements

• Raspberry Pi
• Python 3.3 and up
• WS2811 style (others might work with some modification) individually addressable LED strip
• An MQTT host server. I use CloudMQTT because it's free and easy to set up.

Put something about installing dependencies here

Usage

1. Plug your LED strip's data line into pin 18 of your Raspberry Pi
2. Run pyledserver/run.py. If first time setup, CLI will prompt for MQTT host credentials.
3. To run a plugin on the LED server, you can send a message to your MQTT host in the test topic with the following JSON format:

{
  "message": "[PLUGIN_NAME]",
  "args": 
    {
      "arg1": "[ARG_1]"
    }
}

NOTE: It is important to keep the format of your JSON to have one message string value and a dictionary of values for the args key, even if empty.

Built-in Plugins

PyLEDServer has three built-in plugins:

• solid_color
• ping_pong
• timer

The format for each plugin's MQTT request message are located in each plugin's .py file.

Heres an example on how to activate solid_color:

{
  "message": "solid_color",
  "args": 
    {
      "r": 173,
      "g": 216,
      "b": 230
    }
}

Development

You can reference any existing python file in pyledserver/plugins to get an idea on how the structure should be.
