-Boolean Operators
-=================
-
-These can be used inside the condition of an
-`if <http://arduino.cc/en/Reference/If>`_ statement.
-
-
-
-&& (logical and)
-~~~~~~~~~~~~~~~~
-
-True only if both operands are true, e.g.
-
-::
-
-    if (digitalRead(2) == HIGH  && digitalRead(3) == HIGH) { // read two switches 
-      // ...
-    } 
-
-is true only if both inputs are high.
-
-
-
-\|\| (logical or)
-~~~~~~~~~~~~~~~~~
-
-True if either operand is true, e.g.
-
-::
-
-    if (x > 0 || y > 0) {
-      // ...
-    } 
-
-is true if either x or y is greater than 0.
-
-
-
-! (not)
-~~~~~~~
-
-True if the operand is false, e.g.
-
-::
-
-    if (!x) { 
-      // ...
-    } 
-
-is true if x is false (i.e. if x equals 0).

-
-Warning
--------
-
-Make sure you don't mistake the boolean AND operator, && (double
-ampersand) for the bitwise AND operator & (single ampersand). They
-are entirely different beasts.
-
-
-
-Similarly, do not confuse the boolean \|\| (double pipe) operator
-with the bitwise OR operator \| (single pipe).
-
-
-
-The bitwise not ~ (tilde) looks much different than the boolean not
-! (exclamation point or "bang" as the programmers say) but you
-still have to be sure which one you want where.
-
-
-
-Examples
---------
-
-::
-
-    if (a >= 10 && a <= 20){}   // true if a is between 10 and 20
