@Delta_G

It's the single most common topic on this board and there are TONS of tutorials and threads and all about it.

Yes and 99% of all these tutorials are beaten with

the experts blindness for beginner difficulties

That is the reason why reading one of these tutorials requires

@alto777

Be brave. This is one of those things that is hard until it is easy.

That all these tons of tutorials make it hard to understand has three reasons:

1. NOT emphasizing the fundamental difference between delay() and non-blocking timing which is only BASED on millis(). It needs more than a simple call to function millis().

From a quick reading most newcomers think replace delay() with millis() and you are done
which is totally wrong.

2. this: has been handed down for ages
   but still a very bad example this
   infamous inglorious blink without delay example of the arduino-IDE
   making non-blocking timing unnecessarily difficult to understand through badly chosen variable names, and scattering the variables around in the code.

3. not using an everyday-example with easy to follow numbers that explains all details written out for most easiest understanding

The experienced users here will roll their eyes but I will repeat such postings until the Arduino-team will have replaced this BW-understand-example code with something much better and setup a tutorial that follows the three reasons I have written above

So here it is:

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 …

Additionally here is a short not yet finished tutorial outer high-level circular-repeating coding
which shows the fundamental difference to linear coding / inner low-level repeating coding.

Explaining how to write NON-blocking all time responsive code

Hi Everybody, from time to time I enjoy writing tutorials in my kind and style. My intention is to make it easy to understand. Though I'm aware: of the fact that one way of explaining things is not the best way for everybody. that the best experts about easyness-to-understand are: beginners . I want to encourage especially beginners to ask whatever question comes to their mind. I will use these questions as suggestion to improve the tutorial to become even more easy to understand. The u…
