It is recommended to start with the mother of all Arduino timers, the IDE's BLINKWITHOUTDELAY example.
Using this example, you can see how millis() function works and extend this with some additional functions.

OK the infamous famous "again?"

I explicitly recommend to

NOT

use this badly coded hard to understand The learning child severely neglecting mother of all Arduino-Timers

every week new

1 to 5 new postings "I don't understand millis()-questions"

a first part to explain how non-blocking coding works is posted here.
I'm not satisfied with it yet because there must be more explained how to let do loop() all looping by easy to understand everyday analogons explaining pictures and multiple demo-codes that show how it works on small examples.

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 principle …
