-digitalRead()
-=============
-
-Reads the value from a specified digital pin, either :ref:`HIGH
-<lang-constants-high>` or :ref:`LOW <lang-constants-low>`.

-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.
