# Kaleidoscope-LEDEffect-Rainbow
|
||||
|
||||
Two colorful rainbow effects are implemented by this plugin: one where the
|
||||
rainbow waves through the keys, and another where the LEDs breathe though the
|
||||
colors of a rainbow. The difference is that in the first case, we have all the
|
||||
rainbow colors on display, and it waves through the keyboard. In the second
|
||||
case, we have only one color at a time, for the whole board, and the color
|
||||
cycles through the rainbow's palette.
|
||||
|
||||
## Using the extension
|
||||
|
||||
To use the plugin, include the header, and tell the firmware to use either (or
|
||||
both!) of the effects:
|
||||
|
||||
```c++
|
||||
#include <Kaleidoscope-LEDControl.h>
|
||||
#include <Kaleidoscope-LEDEffect-Rainbow.h>
|
||||
|
||||
KALEIDOSCOPE_INIT_PLUGINS(LEDRainbowEffect, LEDRainbowWaveEffect);
|
||||
|
||||
void setup() {
|
||||
Kaleidoscope.setup();
|
||||
|
||||
LEDRainbowEffect.brightness(150);
|
||||
LEDRainbowWaveEffect.brightness(150);
|
||||
LEDRainbowWaveEffect.update_delay(50);
|
||||
}
|
||||
```
|
||||
|
||||
## Plugin methods
|
||||
|
||||
The plugin provides two objects: `LEDRainbowEffect`, and `LEDRainbowWaveEffect`,
|
||||
both of which provide the following methods:
|
||||
|
||||
### `.brightness([brightness])`
|
||||
|
||||
> Sets (or gets, if called without an argument) the LED brightness for the
|
||||
> effect.
|
||||
>
|
||||
> Defaults to 50.
|
||||
|
||||
### `.update_delay([delay])`
|
||||
|
||||
> Sets (or gets, if called without an argument) the number of milliseconds
|
||||
> between effect updates. Smaller number results in faster rainbows.
|
||||
>
|
||||
> Defaults to 40.

||||
