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.

#include <Kaleidoscope.h>
#include <Kaleidoscope-LEDControl.h>
#include <Kaleidoscope-LED-Wavepool.h>


void setup (){

  WavepoolEffect.idle_timeout = 5000;  // 5 seconds

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:


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).


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.
