node-red-node-blinkstick
|
|
========================
|
|
|
|
A <a href="http://nodered.org" target="_new">Node-RED</a> node to control a <a href="http://www.blinkstick.com/" target="_new">BlinkStick</a>.
|
|
|
|
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 <i><a href="http://www.blinkstick.com/help/tutorials" target="_new">BlinkStick tutorials</a></i> or the <i><a href="https://github.com/arvydas/blinkstick-node" target="_new">node module</a></i> 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
|
|
-----
|
|
|
|
<i><a href="http://www.blinkstick.com" target="_new">BlinkStick</a></i> output node.
|
|
Expects a `msg.payload` with one of:
|
|
|
|
* A hex string <b>"#rrggbb"</b> triple
|
|
* <b>"red,green,blue"</b> three 0-255 values as a string
|
|
* <b>"random"</b> will generate a random color
|
|
* <i><a href="http://www.w3schools.com/html/html_colornames.asp" target="_new">Standard HTML color</a></i> name
|
|
* <b>object</b> 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 }
|
