Is it possible to do a continue in the loop()? For instance, if I wanted to do something every second:
void loop() {
// do all of this normally
if(millis()%1000 != 0) {continue;}
//otherwise
//do
//all
//this
//other
//stuff
}
I know I could reverse it and say if(true){then do all the other code} but I'd much prefer to leave it out of a bracketed section if possible.
Note that I'm not actually checking for something every second, so if the if statement isn't perfect, I don't care.
Just return, loop will be called again a moment later:
if(millis()%1000 != 0)
{
return;
}

Though it is, in my opinion better to put the stuff you do want executed in the body of an if statement.
For future internet voyagers: the millis() % 1000 code is a bad idea. It's unlikely that you'll consistently test millis() exactly on the dot at a 1000 ms increment. You should instead keep a 'nextReading' time that you continuously reset to 1 second from now, and then test if millis() is greater than that to see if you should do your thing.

the TimerOne library might be what you're looking for. It allows to call a routine every x milliseconds....
don't know how precise it is, but worth to give it a try !
