    Hi, the First thing I would do is to scrap the Arduino's pitiful IDE and use Eclipse, I use just plain C with my Arduinos, but I still use the Arduino libraries for the most part. you can do this two ways:

    first is to write using Arduino FrameWork ie. setup() and loop()  (which leaves a lot to be desired

    The second is to write using C (you run into trouble with scoping rules with C++ ).

    I normally keep one function on one page of code which is included  + its header file.

    ie..

    count.h

    int counter;  // thsi could now be a Global but you will have to initialize it before you use it

     

    file count_P.h

    MaxCount = 8;

    MinCount = 1;

    #define UP 1

    #define DOWN 0

     

    file counter.c

    #include counter_P.h

    int counter.c ( int updown ) {

        switch (updown) {

            case UP: {  if( counter = MaxCount ) conter = MinCount;

                               else counter++;

            case DOWN:

    Try to go to the web page: , you will find tutorials, simple projects with diagrams, codes, and videos of the final results. Maybe start by reproducing some simple project you like and then modify it, add features, etc. In this period, when we spend most of our time locked up at home for the pandemic, a hobby like electronics is what it takes to keep our brains active!

    Element14 is an inexhaustible source of interesting and curious projects. Have a good time
