README.md

node-red-node-blinkstick

A Node-RED node to control a BlinkStick.

Pre-requisites

Depending on your operating system you may need to install some extra libraries before installing this node... I.E make sure it works outside of Node-RED first !

For more information see BlinkStick tutorials or the node module documentation.

Raspberry Pi / Debian / Ubuntu

sudo apt-get install -y libudev-dev

You also currently need to create a file /etc/udev/rules.d/80-blinkstick.rules containing

SUBSYSTEMS=="usb", ATTRS{idVendor}=="20a0", ATTRS{idProduct}=="41e5", TAG+="uaccess"

and either reload the udev rules or reboot.

Install

Run the following command in your Node-RED user directory - typically ~/.node-red

npm i node-red-node-blinkstick

Usage

BlinkStick output node. Expects a msg.payload with one of:

A hex string "#rrggbb" triple
"red,green,blue" three 0-255 values as a string
"random" will generate a random color
Standard HTML color name
object can override any of the parameters

An object payload can override any of the settings on the node. Omitted parameters are left intact. For example:

{ 'color': 'blue' }
{ 'task': 'blink', 'color': 'red' }
{ 'task': 'pulse', 'color': 'green', 'duration': 500 }
{ 'task': 'morph', 'color': 'orange', 'duration': 500, 'steps': 20 }
