Then why do you code

      else
        {
         Buffer1[i] = 0;
        }

?

I am a new programmer and do not know well all the code .

How could I change that line of code ?

Also I can delay the signal a few seconds by inserting a different statement ?

You don't change the section of code that I asked about, you remove it.

If you don't understand that, then you are trying to work with code that is too complicated for you.

You have to be able to fully understand exactly what the code is doing.
