I know this is a beginner question because it's about a sketch from a book called Beginning Arduino.
I type in the sketch for the project 2 SOS and when I compile I get this message:
error: 'x3' was not declared in this scope
with this line:
for (int x=0; x3; x++)
I've typed the code exactly as written in the book but it does not work. There are so many typos in this book that I am wondering if perhaps the problem is with how the author wrote it rather than with how I'm writing it.
Any help would be appreciated.
