//| """Basic digital pin support
//|
//| The `digitalio` module contains classes to provide access to basic digital IO.
//|
//| All classes change hardware state and should be deinitialized when they
//| are no longer needed if the program continues after use. To do so, either
//| call :py:meth:`!deinit` or use a context manager. See
//| :ref:`lifetime-and-contextmanagers` for more info.
//|
//| For example::
//|
//|   import digitalio
//|   import board
//|
//|   pin = digitalio.DigitalInOut(board.LED)
//|   print(pin.value)
//|
//| This example will initialize the the device, read
//| :py:data:`~digitalio.DigitalInOut.value` and then
//| :py:meth:`~digitalio.DigitalInOut.deinit` the hardware.
//|
//| Here is blinky::
//|
//|   import time
//|   import digitalio
//|   import board
//|
//|   led = digitalio.DigitalInOut(board.LED)
//|   led.direction = digitalio.Direction.OUTPUT
//|   while True:
//|       led.value = True
//|       time.sleep(0.1)
//|       led.value = False
//|       time.sleep(0.1)
//|

//| Learn guide <https://learn.adafruit.com/circuitpython-essentials/circuitpython-digital-in-out>`_
