Thats interesting, How would I set the case variable? Do I set this as time, e.g if I want 1 sec , do I set first variable as time1 = 1000; when the function returns 1000 the switch case will activate?

No it is totally different.
I guess it will be useful for you to read at first how non-blocking timing works
I wrote a tutorial for that too

Example-code for timing based on millis() easier to understand through the use of example-numbers / avoiding delay()

non-blocking timing. Execute code only from time to time. There are a lot of different ways to learn programming. This thread wants to add another approach that is different to the yet existing ones. UPDATE 06.01.2023 if you are mainly interested in applying non-blocking timing you can do a quick read of this short tutorial / demonstration If you are intersted in understanding the details how it works go on reading here. I use an everyday analogon in this post to explain the basic princip…
