Can somebody look on my program, a piece of program I take from seller I give a piece of own rutine but it still not work. It should fall the points down as snow.
So can somebody give a some debugger or step-trace program to testing?
Tom.
Please post the original code before you started messing with it.
Also, you can start looking into this yourself by using the serial monitor available both in the IDE and the wokwi simulator.
Add
Serial.begin(115200);
to the setup() function, then use
Serial.print("x = "); Serial.println(x);
all over the sketch to see the values of the variables.
Bur really we need to see what you started with and, presumably, had working in front of you.
As for
step-trace program
at this point you may be better off with your finger on the code thinking it through step by step.

I´m sure that somebody change the signals LOW and HIGH in routine because this piece of rutine I take from seller but anyway the program behaved differently than expected.
So I can´t justify why is necessarily call subrutine SetColumns before the instruction digitalWrite and not behind.
Thanks for colaboration.
