This fork has this changes:

The darker mode, when the illuminance is less than 1 i.e. 0, it will go to the target brightness that is 1. The target can be easily changed.

If the file AB.offset have 0 as value. Darker mode is activated and setting brightness will reset to target value 1 when illuminance is less than 1. if the file has value of 1, it will be the normal mode and the screen brightness can be adjusted until the illuminance sensor changes.

easier to change variables and places and chmod 666 /tmp/AB.offset for the user to change modes when script is running as root (systemd service) darker mode as default with normal mode done by typing "echo 1 > /tmp/AB.offset"

they are in autobrightness.sh

I created 4 butttons with launcher panel on xfce in my top bar left corner.

Since I run autobrightness.sh as a systemd service, my custom command in these launchers are from left to right:

Darker mode: bash -c 'echo 0 > /tmp/AB.offset'

Start Autobrightness: touch /tmp/AB.start

Stop Autobrightness: touch /tmp/AB.stop

Default mode: bash -c 'echo 1 > /tmp/AB.offset'

Mac-like-automatic-brightness

A simple script to provide a "Mac" like automatic brightness adjustemnt/ animation

made for the FrameWork laptop

based on 2017 MacBook Pro

read Configuration for detailed informatoion about what options you have to easily customize/ adjust the bightness or animation speed

Requires

brightnessctl

Non 12th Gen Intel Framework Owners

Your sensor has a diffrent range thant the 12th Gen Intel Framework laptop sensors, please see chart bellow

       Type     |  Sensor Rnge | STDScale
 11th Gen Intel | 0 - 3207633  | 1
 12th Gen Intel | 0 - 3984     | 24

Controls

./AutomaticBrightness.sh | Defualt running mode of script

./AutomaticBrightness.sh -i [NUMBER] | Increase the offset your brightness sensors raw reading

./AutomaticBrightness.sh -d [NUMBER] | Decrease the offset your brightness sensors raw reading

/tmp/AB.offset | Stores current offset for the sensor

/tmp/AB.stop | Stops AutomaticBrightness.sh

/tmp/AB.start | Starts stopped AutomaticBrightness.sh

/tmp/AB.kill | Kills AutomaticBrightness.sh

when running you will see a AB.running file and AB.offset in /tmp

Configuring

Light Change The percent of light change needed to be seen by the sensor for it to change the screen brightness

SensorDelay Time in seconds the script will wait to check the sensor for a luminess change after the animation (LevelSteps * AnimationDelay)

SensorToDisplayScale The ratio from sensor to screen brighness, recommended minimum 24 for 12th gen framework laptops. Increasing the value will give a brighter screen for the amount of light in the room/ enviroment

LevelSteps Sets amount of brightness steps, recomended to match refeshrate

AnimationDelay Speed of the brightness animation(delay between each step), recomended screen refreshrate in seconds

MaxScreenBrightness The highest value your screen supports, check /sys/class/backlight/intel_backlight/max_brightness on framework laptops

MinimunBrightness The minimum screen brightness, recomended minumim 001 so the backlight dosn't turn off

~~ Other things to note

Light The file where your lightsensor has its current value

CurrentBirghtness The file where your screen stores its current brightness
