class ``Pin``
===========================

**Example**

.. code-block:: python
    
    # Import Pin class
    from robot_hat import Pin

    # Create Pin object with numeric pin numbering and default input pullup enabled
    d0 = Pin(0, Pin.IN, Pin.PULL_UP)
    # Create Pin object with named pin numbering
    d1 = Pin('D1')

    # read value
    value0 = d0.value()
    value1 = d1.value()
    print(value0, value1)

    # write value
    d0.value(1) # force input to output
    d1.value(0)

    # set pin high/low
    d0.high()
    d1.off()

    # set interrupt
    led = Pin('LED', Pin.OUT)
    switch = Pin('SW', Pin.IN, Pin.PULL_DOWN)
    def onPressed(chn):
        led.value(not switch.value())
    switch.irq(handler=onPressed, trigger=Pin.IRQ_RISING_FALLING)
