LockDots:
How would starting that function starting with:
void stopSketch(void)Differ from starting it with:
void stopSketch()
The void stopSketch(void) is telling the compiler when it first compiles this function that it returns no value back to the calling program and requires no argument to be passed to it when it is called by the program.
During use in your sketch you just write stopSketch() and be done with it.
