MMM-PiLights

MagicMirror Module to control a led strip attached to a Raspberry Pi

Requirements

This module is specifically meant for the Raspberry Pi system, using SPI and a LPD8806 or WS2801 LED strip. It may be compatible with other LED strips, but this has not been tested.

Buy the LPD8806 LED Strip here and learn how to connect it here

If using Raspbian, you will need to enable SPI:

sudo raspi-config

then navigate to Advanced options and enable SPI

Module installation

Clone the module and npm install:

cd ~/MagicMirror/modules
git clone https://github.com/jc21/MMM-PiLights.git
cd MMM-PiLights
npm install

Add the module config to ~/MagicMirror/config/config.js

modules: [
    {
        module: 'MMM-PiLights',
        config: {
            ledCount: 64,
            type: 'ws2801', // 'ws2801' or 'lpd8806'
            bus: 0, 
            device: 0,
            brightness: 1.0 // between 0.0 and 1.0
        }
    }
]

Module Configuration Options

Option	Type	Default	Description
ledCount	Integer	64	Number LEDs on your strip
type	String	ws2801	The LED strip type, either 'ws2801' or 'lpd8806'
bus	Integer	0	The SPI bus number for your LED strip
device	Integer	0	The SPI device number for your LED strip
brightness	Float	0.0	The LED strip brightness (between 0.0 and 1.0)

Trigger from another module

If you're developing a module and want to trigger a light sequence, here's an example of what you'd use in your module:

this.sendNotification('PILIGHTS_SEQUENCE', 'blue_pulse');

My other MagicMirror module is able to trigger light sequences with notifications: MMM-IFTTT

Trigger from a endpoint

The GET endpoint is pretty simple:

http://yourmagicmirror/PiLights?sequence=blue_pulse

From the command line:

curl -X GET "http://yourmagicmirror/PiLights?sequence=blue_pulse"

Available Sequences

• white_pulse
• blue_pulse
• lightblue_pulse
• red_pulse
• green_pulse
• orange_pulse
• pink_pulse
