+{} Curly Braces
+===============
+
+Curly braces (also referred to as just "braces" or as "curly
+brackets") are a major part of the C programming language. They are
+used in several different constructs, outlined below, and this can
+sometimes be confusing for beginners.
+
+
+
+An opening curly brace "{" must always be followed by a closing
+curly brace "}". This is a condition that is often referred to as
+the braces being balanced. The Arduino IDE (integrated development
+environment) includes a convenient feature to check the balance of
+curly braces. Just select a brace, or even click the insertion
+point immediately following a brace, and its logical companion will
+be highlighted.
+
+
+
+At present this feature is slightly buggy as the IDE will often
+find (incorrectly) a brace in text that has been "commented out."
+
+
+
+Beginning programmers, and programmers coming to C from the BASIC
+language often find using braces confusing or daunting. After all,
+the same curly braces replace the RETURN statement in a subroutine
+(function), the ENDIF statement in a conditional and the NEXT
+statement in a FOR loop.
+
+
+
+Because the use of the curly brace is so varied, it is good
+programming practice to type the closing brace immediately after
+typing the opening brace when inserting a construct which requires
+curly braces. Then insert some carriage returns between your braces
+and begin inserting statements. Your braces, and your attitude,
+will never become unbalanced.
+
+
+
+Unbalanced braces can often lead to cryptic, impenetrable compiler
+errors that can sometimes be hard to track down in a large program.
+Because of their varied usages, braces are also incredibly
+important to the syntax of a program and moving a brace one or two
+lines will often dramatically affect the meaning of a program.

+
+**The main uses of curly braces**
+---------------------------------
+
+Functions
+---------
+
+::
+
+      void myfunction(datatype argument){
+        statements(s)
+      }
+
+
+
+Loops
+-----
+
+::
+
+      while (boolean expression)
+      {
+         statement(s)
+      }
+    
+      do
+      {
+         statement(s)
+      } while (boolean expression);
+    
+      for (initialisation; termination condition; incrementing expr)
+      {
+         statement(s)
+      } 
+
+
+
+Conditional statements
+----------------------
+
+
+
+::
+
+      if (boolean expression)
+      {
+         statement(s)
+      }
+    
+      else if (boolean expression)
+      {
+         statement(s)
+      } 
+      else
+      {
+         statement(s)
+      }
