VideoLiam:
One question I have is, are the ' // ' flagged lines which denote comments actually compiled in to the final code or are they stripped out, from the compiled code passed to the arduino?
No, of course they are not compiled into code, they are just that, "comments" for the programmer
Would stipping them out save space.
No.
Also would my sytax for varible labelling make a difference to mememory allocation. For example would
a1 = 2
take less memory than
Answer1 = 2
Again no. Those variables are only readable in that form in the text of the source code of your script.
Pertinant when the 5 extra characters can be repeated dozens of time throughout the programme.
Come again? :~
