WLED/usermods/usermod_rotary_brightness_color

Rotary Encoder (Brightness and Color)

V2 usermod that enables changing brightness and color using a rotary encoder change between modes by pressing a button (many encoders have one included)

it will wait for AUTOSAVE_SETTLE_MS milliseconds. a "settle" period in case there are other changes (any change will extend the "settle" period).

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.
