+.. _lang-digitalread:
+
+digitalRead()
+=============
+
+Description
+-----------
+
+Reads the value from a specified digital pin, either :ref:`HIGH
+<lang-constants-high>` or :ref:`LOW <lang-constants-low>`.
+
+
+Library Documentation
+---------------------
+
+.. doxygenfunction:: digitalRead
+
+
+Example
+-------
+
+The following example turns the LED on when the button is pressed::
+
+    int ledPin = 13;     // LED connected to Maple pin 13
+    int buttonPin = 38;  // BUT connected to Maple pin 38
+
+    void setup() {
+      pinMode(ledPin, OUTPUT);
+      pinMode(buttonPin, INPUT);
+    }
+
+    void loop() {
+      int val = digitalRead(buttonPin);   // reads the input pin
+      digitalWrite(ledPin, val);
+    }
+
+Note
+----
+
+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).
+
+Arduino Compatibility
+---------------------
+
+The Maple version of ``digitalRead()`` is compatible with Arduino.
