+setup()
+=======
+
+The setup() function is called when a sketch starts. Use it to
+initialize variables, pin modes, start using libraries, etc. The
+setup function will only run once, after each powerup or reset of
+the Arduino board.
+
+
+
+Example
+~~~~~~~
+
+::
+
+     
+    int buttonPin = 3;
+    
+    void setup()
+    {
+      Serial.begin(9600);
+      pinMode(buttonPin, INPUT);
+    }
+    
+    void loop()
+    {
+      // ...
+    }
