# Light Switch Widget

Whis this widget I wanted to create a solution to quickly en-/disable the LCD backlight and even change the brightness.  
In addition it shows the lock status with the option to personalize the lock icon with a tiny image.


## Control ##

* __On / off__  
  Single touch the widget to en-/disable the backlight.
* __Change brightness__ _(can be disabled)_  
  First touch the widget and then retouch the screen and drag up/down until you reach your wished brigthness.
* __Double tap to flash backlight__ _(can be disabled)_  
  By defaut you can double tap on the right side of your bangle to flash the backlight for a short duration.  
  (While the backlight is active your bangle will be unlocked.)
* __Double tap to unlock__ _(disabled by default)_  
  If a side is defined in the app settings, your bangle will be unlocked if you double tab on that side.
