 == Cast ==
 Cast is a way of converting one type of data, to another type,
   * such as float to int
-  * ([type])[var]
+  * $([type])[var]
   * type is things like float or int
   * var is any variable or constant
   * Example (to change a float brightness to a int brightness
-  * float bright = sensorValue * (255.0 / 1023.0);
+<code>
-  * int bint; // a way to define an int name, but give no value
+float bright = sensorValue * (255.0 / 1023.0);
-  * float bflo; // define float name, but give no value
+int bint; // a way to define an int name, but give no value
-  * bflo = bright; // sets what value the float is
+float bflo; // define float name, but give no value
-  * bint = (int)bflo; // this is the cast directive
+bflo = bright; // sets what value the float is
-  * analogWrite(led, bint); // for this example, it would cast the light as an int through a pwm pin and allow it to be an integer between 0-255
+bint = (int)bflo; // this is the cast directive
-==== Before void setup: ====
+analogWrite(led, bint); // for this example, it would cast the light as an int through a pwm pin and allow it to be an integer between 0-255

 Before setup you can define things such as int
