Way to increase screen brightness in AppleScript?

[CharType]

I'm trying to write an AppleScript to increase the brightness on my MacBook. Is there a way to do this from AppleScript and if so how? I did some searching and I found and tried the following code:

tell application "System Events"
    key code 107
end tell

But when I entered this into Script Editor and pressed the "Run the Script" button, it just beeped and didn't do anything.

Try the script in the 2nd post in this Stackoverflow question. It's a lot more generic and doesn't rely on varying/changing key codes Additionally, on the latest MBP with touch bar, the brightness is a similar slider as the one in system preferences, so in theory that solution should work on every Mac.

Is there anything useful you can use in either of these?:

You mean this one?

tell application "System Preferences"
	if it is running then
		quit
	end if
end tell
delay 0.2
activate application "System Preferences"
tell application "System Events"
	tell process "System Preferences"
		click button "Displays" of scroll area 1 of window "System Preferences"
		delay 1
		set value of value indicator 1 of slider 1 of group 2 of tab group 1 of window "Built-in Retina Display" to 0.75
	end tell
	delay 1
	quit application "System Preferences"
end tell

That didn't work. I got an error message: error "System Events got an error: Can’t get window \"System Preferences\" of process \"System Preferences\"." number -1728 from window "System Preferences" of process "System Preferences"

No. I tried all of the scripts in those threads, nothing worked. The closest I got was this script:

tell application "System Preferences"
    reveal anchor "displaysDisplayTab" of pane "com.apple.preference.displays"
end tell
tell application "System Events" to tell process "System Preferences" to tell window "Built-in Retina Display"
    set value of value indicator 1 of slider 1 of group 2 of tab group 1 to 0.75
end tell
quit application "System Preferences"

That opened the Built-in Retina Display in System Preferences, but it didn't move the slider. I got the following error message: error "System Events got an error: Can’t get group 2 of tab group 1 of window \"Built-in Retina Display\" of process \"System Preferences\". Invalid index." number -1719 from group 2 of tab group 1 of window "Built-in Retina Display" of process "System Preferences"

When using an external keyboard, the brightness key codes change from 107 and 113 to 145 and 144 respectively, to lower/raise the brightness level.

You may also want to check out this command line tool: https://github.com/nriley/brightness
It allows you to specify what percent brightness you want, which is probably more useful.

RazorEdge's solution also has the benefit of allowing you to set a brightness percentage but unfortunately that solution will only work on a MBP with retina display.
