Improvements to BlinkStick node
* Ability to select BlinkStick by serial number * Look up serial numbers of connected BlinkSticks * Ability to set blink, morph and pulse animations * Ability to control the parameters of those animations like duration, * steps, repeats and delay * Repeat blink and pulse animation until new payload is received * Automatically find BlinkStick if it was removed and then plugged back in * Connectivity status when "Node Status" is enabled in the menu * Override parameters with payload object * Improved text in the info pane

<p>BlinkStick output node. Expects a <b>msg.payload</b> with either a hex string #rrggbb triple or red,green,blue as three 0-255 values.
|

It can also accept <i><a href="http://www.w3schools.com/html/html_colornames.asp" target="_new">standard HTML colour</a></i> names</p>
|
||||
<p><b>NOTE:</b> currently only works with a single BlinkStick. (As it uses the findFirst() function to attach).</p>

|
||||
<li><b>"red,green,blue"</b> three 0-255 values as a string</li>

Usage
|
||||
-----
|
||||
|
||||
The BlinkStick output node expects a <b>msg.payload</b> with either a hex string #rrggbb triple or red,green,blue as three 0-255 values.
|
||||
<i><a href="http://www.blinkstick.com" target="_new">BlinkStick</a></i> output node. Expects a <b>msg.payload</b> 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
|
||||
|
||||
It can also accept <i><a href="http://www.w3schools.com/html/html_colornames.asp" target="_new">standard HTML colour</a></i> names.
|
||||
An object payload can override any of the settings on the node. Omitted parameters are left intact. For example:
|
||||
|
||||
<b>NOTE:</b> currently only works with a single BlinkStick. (As it uses the findFirst() function to attach).
|
||||
{ 'color': 'blue' }
|
||||
{ 'task': 'blink', 'color': 'red' }
|
||||
{ 'task': 'pulse', 'color': 'gree', 'duration': 500 }
|
||||
{ 'task': 'morph', 'color': 'orange', 'duration': 500, 'steps': 20 }
