# LED-Wavepool
The `WavepoolEffect` plugin makes waves of light splash out from each keypress.
When idle, it will also simulate gentle rainfall on the keyboard.
## Using the plugin
To use the plugin, one needs to include the header and select the effect.
```c++
#include <Kaleidoscope.h>
#include <Kaleidoscope-LEDControl.h>
#include <Kaleidoscope-LED-Wavepool.h>
KALEIDOSCOPE_INIT_PLUGINS(LEDControl, WavepoolEffect);
void setup (){
Kaleidoscope.setup();
WavepoolEffect.idle_timeout = 5000; // 5 seconds
WavepoolEffect.activate();
}
```
It is recommended to place the activation of the plugin as early as possible, so
the plugin can catch all relevant key presses.
## Plugin properties
The plugin provides the `WavepoolEffect` object, which has the following
properties:
### `.idle_timeout`
> When to keys are being pressed, light will periodically splash across
> the keyboard. This value sets the delay in ms before that starts.
>
> To disable the idle animation entirely, set this to 0.
>
> Default is 5000 (5 seconds).
### `.ripple_hue`
> The Hue of the ripple animation. If set, the light splashing across the
> keyboard will use this value instead of all colors of the rainbow.
>
> Setting it to the special value of `WavepoolEffect.rainbow_hue` will cause the
> plugin to use all colors again.
>
> Defaults to `WavepoolEffect.rainbow_hue`.
