/*
|
|
* That usermod implements support of simple hand gestures with VL53L0X sensor: on/off and brightness correction.
|
|
* It can be useful for kitchen strips to avoid any touches.
|
|
* - on/off - just swipe a hand below your sensor ("shortPressAction" is called and can be customized through WLED macros)
|
|
* - brightness correction - keep your hand below sensor for 1 second to switch to "brightness" mode.
|
|
* Configure brightness by changing distance to the sensor (see parameters below for customization).
|
|
* "macroLongPress" is also called here.
|
|
*
|
|
* Enabling this mod usermod:
|
|
* 1. Attach VL53L0X sensor to i2c pins according to default pins for your board.
|
|
* 2. Add "-D USERMOD_VL53L0X_GESTURES" to your build flags at platformio.ini (plaformio_override.ini) for needed environment.
|
|
* In my case, for example: build_flags = ${common.build_flags_esp8266} -D RLYPIN=12 -D USERMOD_VL53L0X_GESTURES
|
|
* 3. Add "pololu/VL53L0X" dependency to lib_deps like this:
|
|
* lib_deps = ${env.lib_deps}
|
|
* pololu/VL53L0X @ ^1.3.0
