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 :ref:`millis() <arduino-millis>` function -and the "Blink Without Delay" sketch cited :ref:`below -<arduino-delay-seealso>`\ . More knowledgeable programmers usually -avoid the use of ``delay()`` for timing of events longer than tens of -milliseconds, unless the sketch is very simple. - -Certain things *do* go on while the ``delay()`` function is -controlling the STM32 chip, however, because the delay function does -not disable interrupts.
