+
+Assignment Operator (``=``)
+===========================
+
+Stores the value to the right of the equal sign in the variable to
+the left of the equal sign.
+
+The single equal sign in the C++ programming language is called the
+assignment operator. It has a different meaning than in algebra
+class, where it indicated an equation or equality. The assignment
+operator tells the microcontroller to evaluate whatever value or
+expression is on the right side of the equal sign, and store it in
+the variable to the left of the equal sign [#fgross]_.
+
+Example
+-------
+
+::
+
+     int sensVal;                  // declare an integer variable named sensVal
+     sensVal = analogRead(0);      // store the (digitized) input voltage at analog pin 0 in sensVal
+
+Programming Tips
+----------------
+
+The variable on the left side of the assignment operator (``=`` sign)
+needs to be able to hold the value stored in it. If it is not large
+enough to hold a value, the value stored in the variable will be
+incorrect.
+
+Don't confuse the assignment operator ``=`` (single equal sign) with
+the comparison operator ``==`` (double equal signs), which evaluates
+whether two expressions are equal.
+
+Arduino Compatibility
+---------------------
+
+Assignments on the Maple are identical to those on Arduino.
