For example, an :ref:`analog input -` could be tested, with one action taken if the -input was less than 500, and another action taken if the input was 500 -or greater. The code would look like this:: - - if (pinFiveInput < 500) { - // action A - } else { - // action B - } - -``else`` can precede another ``if`` test, so that multiple, mutually -exclusive tests can be run at the same time. - -Each test will proceed to the next one until a true test is -encountered.
