I don't want the screen to be always on because I'm trying to make an alarm clock. Therefore the screen has to go inactive ("dark") eventually - else I can't sleep :).
The "snooze" button of the UT clock app is pretty tiny. When I finally found it I'm wide awake.
Therefore I'm trying to make an app with a huge "snooze" button that's filling the whole screen so I just have to tap on the display to hit it. But the screen has to be active to do so.
I want my script to do what the UT-clock-app does: Activate the screen when the alarm goes off.
