-Discussion
-----------
-
-If the pin has been configured as an ``OUTPUT`` with :ref:`pinMode()
-<lang-pinmode>` its voltage will be set to the corresponding value:
-3.3V for ``HIGH``, and 0V (ground) for ``LOW``.
-
-.. TODO make the following paragraphs true, but refer the reader to
-.. INPUT_PULLUP and INPUT_PULLDOWN:
-
-If the pin is configured as an ``INPUT``, writing a ``HIGH`` value
-with ``digitalWrite()`` will enable an internal pullup resistor.
-Writing ``LOW`` will disable the pullup. The pullup resistor is enough
-to light an LED dimly, so if LEDs appear to work, but very dimly, this
-is a likely cause. The remedy is to set the pin to an output with the
-:ref:`pinMode() <lang-pinmode>` function.
-
-.. note:: Pin 13 is harder to use as an input than the other pins
-   because it has an LED and resistor soldered to it in series. If you
-   enable its internal pull-up resistor, it will likely hang at around
-   1.1V instead of the expected 3.3V because the onboard LED and
-   series resistor pull the voltage level down. If you must use pin 13
-   as a digital input, use an external pull-down resistor.

-Example
--------
-
-The following example sets pin 13 to ``HIGH``, makes a one-second-long
-delay, sets the pin back to ``LOW``, and delays again, causing a
-blinking pattern::
-
-
-    int ledPin = 13;                 // LED connected to digital pin 13
-
-    void setup() {
-      pinMode(ledPin, OUTPUT);      // sets the digital pin as output
-    }
-
-    void loop() {
-      digitalWrite(ledPin, HIGH);   // sets the LED on
-      delay(1000);                  // waits for a second
-      digitalWrite(ledPin, LOW);    // sets the LED off
-      delay(1000);                  // waits for a second
-    }
