Inline link to Blink Without Delay sketch

I couldn't find the link immediately to the sketch sited below (because below it's listed as an example), so I just inlined the sketch. And then I inlined and summarized the idea of the sketch, too.

 === Notes and Warnings
-While it is easy to create a blinking LED with the `delay()` function, and many sketches use short delays for such tasks as switch debouncing, the use of `delay()` in a sketch has significant drawbacks. No other reading of sensors, mathematical calculations, or pin manipulation can go on during the delay function, so in effect, it brings most other activity to a halt. For alternative approaches to controlling timing see the link:../millis[millis()] function and the sketch sited below. More knowledgeable programmers usually avoid the use of `delay()` for timing of events longer than 10's of milliseconds unless the Arduino sketch is very simple.

For alternative approaches to controlling timing see the link:http://arduino.cc/en/Tutorial/BlinkWithoutDelay[Blink Without Delay] sketch, which loops, polling the link:../millis[millis()] function until enough time has elapsed.

 Certain things do go on while the delay() function is controlling the Atmega chip however, because the delay function does not disable interrupts. Serial communication that appears at the RX pin is recorded, PWM (link:../../analog-io/analogwrite[analogWrite]) values and pin states are maintained, and link:../../external-interrupts/attachinterrupt[interrupts] will work as they should.
