|
====================
|
|
|
|
A <a href="http://nodered.org" target="_new">Node-RED</a> node to control a <a href="http://thingm.com/products/blink-1/" target="_new">Thingm Blink(1)</a> LED.
|
|
|
|
Pre-requisites
|
|
--------------
|
|
|
|
As the blink1 is a USB HID device you may need some extra hardware libraries as
|
|
documented <a href="https://www.npmjs.com/package/node-blink1" target="_new">here</a>
|
|
and <a href="https://github.com/todbot/blink1/blob/master/linux/51-blink1.rules" target="_new">here</a>.
|
|
|
|
Specifically Ubuntu/Debian/Raspbian users may need to
|
|
|
|
sudo apt-get install libusb-1.0-0-dev
|
|
|
|
and also setup these udev rules in `/etc/udev/rules.d/51-blink1.rules`
|
|
|
|
SUBSYSTEM=="input", GROUP="input", MODE="0666"
|
|
SUBSYSTEM=="usb", ATTRS{idVendor}=="27b8", ATTRS{idProduct}=="01ed", MODE:="666", GROUP="plugdev"
|
|
|
|
Install
|
|
-------
|
|
|
|
Run the following command in your Node-RED user directory - typically `~/.node-red`
|
|
|
|
npm i node-red-node-blink1
|
|
|
|
Usage
|
|
-----
|
|
|
|
__Out__
|
|
Sends the `msg.payload` to a Thingm Blink(1) LED device. The payload can be any of the following:
|
|
|
|
- a three part csv string of r,g,b - e.g. red is 255,0,0
|
|
- a hex colour #rrggbb - e.g. green is #00FF00
|
|
- a <a href="http://www.cheerlights.com/control-cheerlights">@cheerlights</a> colour name - e.g. blue
|
|
|
|
The colours it accepts are - red, amber, green, blue, cyan, magenta, yellow, orange, pink, purple, white, warmwhite (or oldlace), black, (and off)
|
|
|
|
__In__
|
|
Outputs the current color value of the Blink(1) LED device in the `msg.payload` with the r,g,b values as an array e.g. [255,0,0].
|
|
|
|
If the Blink(1) is off the device returns 0,0,0. Instead of [0,0,0] the node returns "off". |
