Control RGB led strips with traveling and morphing "dudes" (fm sine waves). Supports SK9822 (e.g. Adafruit DotStar) and WS281(X) (e.g. Adafruit NeoPixel) right now. Tested on a Raspberry Pi Zero W with Adafruit DotStar strip via SPI as well as Adafruit NeoPixel strip via PWM & DMA on GPIO18.
| Option | Required | Description |
|---|---|---|
| ledType | yes | dotstar or SK9822, neopixel or ws281x |
| stripLength | yes | int total number of LEDs |
| schedule | list of times to be "on", see below for format | |
| dudes | list of "dudes"; see implementation and examples for details |
Schedule item should be in form:
state: ON
start: [h, m]
end: [h, m]Where h is int hours (0 - 23) and m is int minutes (0 - 59)
Only argument is config file
node run.js config/halloween-dotstar.yml
yarn install # or npm install
I use pm2 to start on boot:
yarn global add pm2 # or npm install -g pm2
pm2 startup # follow instructions
pm2 start --name led-dudes run.js -- config/halloween-dotstar.yml
pm2 saveNote that you will need to run as root if you use neopixel (WS281x) mode. For example:
sudo startup
sudo pm2 start --name led-dudes run.js -- config/halloween-neopixel.yml
sudo pm2 save
