<p class='vspace'></p><h2>char</h2>
<h4>Description</h4>
<p>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").
</p>
<p class='vspace'></p><p>Characters are stored as numbers however. You can see the specific encoding in the <a class='wikilink' href='ASCIIchart.html'>ASCII chart</a>. 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 <a class='wikilink' href='Serial_Println.html'>Serial.println</a> reference for more on how characters are translated to numbers.
</p>
<p class='vspace'></p><p>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 <em>byte</em> data type.
</p>
<p class='vspace'></p><h4>Example</h4>
<pre> char myChar = 'A';
char myChar = 65; // both are equivalent
</pre>
