-Boolean Operators
-=================
-
-These can be used inside the condition of an :ref:`if <arduino-if>`
-statement.  Evaluate to :ref:`true <arduino-constants-true>` or
-:ref:`false <arduino-constants-false>`.

-.. _arduino-boolean-and:
-
-&& (logical and)
-----------------
-
-True only if both operands are true.  For example::
-
-    if (digitalRead(2) == HIGH  && digitalRead(3) == HIGH) { // read two switches
-      // ...
-    }
-
-is true only if both inputs are high.  Another example::
-
-    if (a >= 10 && a <= 20){}   // true if a is between 10 and 20
-
-**Be careful** not to say ``10 <= a <= 20``!  This won't work the way
-you want.  You have to separately test whether ``a`` is at least 10
-using ``a >= 10``, then test whether ``a`` is at most 20 using ``a <=
-20``, then combine the results using ``&&``.
-
-
-.. _arduino-boolean-or:
-
-\|\| (logical or)
------------------
-
-True if either operand is true.  For example::
-
-    if (x > 0 || y > 0) {
-      // ...
-    }
-
-is true if either ``x`` or ``y`` is greater than 0.
-
-.. _arduino-boolean-not:
-
-! (logical not)
----------------
-
-True if the operand is false.  For example::
-
-    if (!x) {
-      // ...
-    }
-
-is true if ``x`` is false (i.e. if ``x`` is zero).
-
-Some Advice
------------
-
-.. warning::
-
-   Make sure you don't mistake the boolean AND operator ``&&``
-   (double ampersand) for the :ref:`bitwise AND operator
-   <arduino-bitwisemath-and>` ``&`` (single ampersand). They are
-   entirely different beasts.
-
-   Similarly, do not confuse the boolean OR operator ``||`` (double
-   pipe) with the :ref:`bitwise OR operator <arduino-bitwisemath-or>`
-   ``|`` (single pipe).
-
-   The :ref:`bitwise NOT operator <arduino-bitwisemath-not>` ``~``
-   (tilde) looks much different than the boolean not operator ``!``
-   (exclamation point, or "bang", as some programmers say), but you
-   still have to be sure which one you want.
