 Example
 -------
 
-::
+The following example turns the LED on when the button is pressed::
 
-     
-    int ledPin = 13; // LED connected to digital pin 13
-    int inPin = 7;   // pushbutton connected to digital pin 7
-    int val = 0;     // variable to store the read value
+    int ledPin = 13;     // LED connected to Maple pin 13
+    int buttonPin = 38;  // BUT connected to Maple pin 38
     
-    void setup()
-    {
-      pinMode(ledPin, OUTPUT);      // sets the digital pin 13 as output
-      pinMode(inPin, INPUT);      // sets the digital pin 7 as input
+    void setup() {
+      pinMode(ledPin, OUTPUT);
+      pinMode(buttonPin, INPUT);
     }
     
-    void loop()
-    {
-      val = digitalRead(inPin);   // read the input pin
-      digitalWrite(ledPin, val);    // sets the LED to the button's value
+    void loop() {
+      int val = digitalRead(buttonPin);   // reads the input pin
+      digitalWrite(ledPin, val);
     }
 
-
-
-Sets pin 13 to the same value as the pin 7, which is an input.
-
-
-
 Note
 ----
 
-If the pin isn't connected to anything, digitalRead() can return
-either HIGH or LOW (and this can change randomly).
-
-
+If the pin isn't connected to anything, ``digitalRead()`` can return
+either HIGH or LOW (and this can change in a way that seems random).
 
-The analog input pins can be used as digital pins, referred to as
-A0, A1, etc.
+Arduino Compatibility
+---------------------
 
+The Maple version of ``digitalRead()`` is compatible with Arduino.
