|`BACKLIGHT_LEVELS` |`3` |The number of brightness levels (maximum 31 excluding off) |

|`BREATHING_PERIOD` |`6` |The length of one backlight "breath" in seconds |
|

|`BACKLIGHT_ON_STATE` |`1` |The state of the backlight pin when the backlight is "on" - `1` for high, `0` for low |
|

|`BACKLIGHT_LIMIT_VAL` |`255` |The maximum duty cycle of the backlight -- `255` allows for full brightness, any lower will decrease the maximum.|

Unless you are designing your own keyboard, you generally should not need to change the `BACKLIGHT_PIN` or `BACKLIGHT_ON_STATE`.
