class ``Servo``
=============================

**Example**

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

    # Create Servo object with PWM object
    servo0 = Servo("P0")

    # Set servo to position 0, here 0 is the center position,
    # angle ranges from -90 to 90
    servo0.angle(0)

    # Sweep servo from 0 to 90 degrees, then 90 to -90 degrees, finally back to 0
    import time
    for i in range(0, 91):
        servo0.angle(i)
        time.sleep(0.05)
    for i in range(90, -91, -1):
        servo0.angle(i)
        time.sleep(0.05)
    for i in range(-90, 1):
        servo0.angle(i)
        time.sleep(0.05)


    # Servos are all controls with pulse width, some
    # from 500 ~ 2500 like most from SunFounder.
    # You can directly set the pulse width

    # Set servo to 1500 pulse width (-90 degree)
    servo0.pulse_width_time(500)
    # Set servo to 1500 pulse width (0 degree)
    servo0.pulse_width_time(1500)
    # Set servo to 1500 pulse width (90 degree)
    servo0.pulse_width_time(2500)
