Haptic
======

The `Haptic <http://mbientlab.com/docs/metawear/csharp/1/interfaceMbientLab_1_1MetaWear_1_1Peripheral_1_1IHaptic.html>`_ class interacts with the haptic driver pin to 
drive a buzzer or motor.  Circuit diagrams for the haptic driver are in section 8 of the 
`product spec <https://mbientlab.com/docs/MetaWearPPSv0.7.pdf>`_.

::

    using MbientLab.MetaWear.Peripheral;
    
    // Run a buzzer for 500ms
    metawear.GetModule<IHaptic>().StartBuzzer(500);

    // Run a motor for 1000ms at 50% strength
    metawear.GetModule<IHaptic>().StartMotor(1000, 50f);
