A function to compare a sensor input to a threshold

The return keyword is handy to test a section of code without having to "comment out" large sections of possibly buggy code.
void loop() {
// brilliant code idea to test here
return;
// the rest of a dysfunctional sketch here
// this code will never be executed
}
