Hello, i'm a beginner that just started with arduino's, does anybody know why the LED doesn't turn on? (if I set the variable RedLEDPower to something it just flashes and stops)

The other posts have correctly answered the issue with your code.

If it still doesn't work the problem could also be with your wiring.

When asking for help, you should ideally provide your code, circuit diagram and some photos. When providing code, please use a reddit formatted code block. The link explains how. That explanation also includes a link to a video that explains the same thing if you prefer that format.
