# Rotary Encoder (Brightness and Color)
2022-12-10 15:12:55 +00:00
V2 usermod that enables changing brightness and color using a rotary encoder

It will additionally load preset AUTOSAVE_PRESET_NUM at startup.
during the first `loop()` . Reasoning below.
AutoSaveUsermod is standalone, but if FourLineDisplayUsermod is installed, it will notify the user of the saved changes.

Note: WLED doesn't respect the brightness of the preset being auto loaded, so the AutoSaveUsermod will set the AUTOSAVE_PRESET_NUM preset in the first loop, so brightness IS honored. This means WLED will effectively ignore Default brightness and Apply N preset at boot when the AutoSaveUsermod is installed.

## Installation
define `USERMOD_ROTARY_ENCODER_BRIGHTNESS_COLOR` e.g.
`#define USERMOD_ROTARY_ENCODER_BRIGHTNESS_COLOR` in my_config.h
or add `-D USERMOD_ROTARY_ENCODER_BRIGHTNESS_COLOR` to `build_flags` in platformio_override.ini
### Define Your Options
Open Usermod Settings in WLED to change settings:
`fadeAmount` - how many points to fade the Neopixel with each step of the rotary encoder (default 5)
`pin[3]` - pins to connect to the rotary encoder:
- `pin[0]` is pin A on your rotary encoder
- `pin[1]` is pin B on your rotary encoder
- `pin[2]` is the button on your rotary encoder (optional, set to -1 to disable the button and the rotary encoder will control brightness only)
### PlatformIO requirements
No special requirements.
## Change Log
2021-07
* Upgraded to work with the latest WLED code, and make settings configurable in Usermod Settings
