-====
-
-Description
------------
-
-A data type that takes up 1 byte of memory that stores a character
-value. Character literals are written in single quotes, like this:
-'A' (for multiple characters - strings - use double quotes:
-"ABC").
-
-
-
-Characters are stored as numbers however. You can see the specific
-encoding in the
-`ASCII chart <http://arduino.cc/en/Reference/ASCIIchart>`_. This
-means that it is possible to do arithmetic on characters, in which
-the ASCII value of the character is used (e.g. 'A' + 1 has the
-value 66, since the ASCII value of the capital letter A is 65). See
-`Serial.println <http://arduino.cc/en/Serial/Println>`_ reference
-for more on how characters are translated to numbers.
-
-
-
-The char datatype is a signed type, meaning that it encodes numbers
-from -128 to 127. For an unsigned, one-byte (8 bit) data type, use
-the *byte* data type.
-
-
-
-Example
--------
-
-::
-
- char myChar = 'A';
- char myChar = 65; // both are equivalent
