+unsigned long
+=============
+
+Description
+-----------
+
+Unsigned long variables are extended size variables for number
+storage, and store 32 bits (4 bytes). Unlike standard longs
+unsigned longs won't store negative numbers, making their range
+from 0 to 4,294,967,295 (2^32 - 1).
+
+
+
+Example
+-------
+
+::
+
+    unsigned long time;
+    
+    void setup()
+    {
+      Serial.begin(9600);
+    }
+    
+    void loop()
+    {
+      Serial.print("Time: ");
+      time = millis();
+      //prints time since program started
+      Serial.println(time);
+      // wait a second so as not to send massive amounts of data
+      delay(1000);
+    }
+
+Syntax
+------
+
+::
+
+        unsigned long var = val;
+
+
+
+
+-  var - your long variable name
+-  val - the value you assign to that variable
