    I am just wondering how the digital dimmers work? Do they employ triacs?

    I would also like to know if it is possible to control the digital dimmers via microcontroller?

    Regards

    It might. Open one up and see.

    Yes it is.

    If you're using a digital controller for an AC power source, I bet there is a triac in there.
    Dimming a DC power source might be done with pulse width modulation.
    I suspect that the digital part might only be the display in some cases.
    That's because I do not understand some parts of the question.
    Perhaps you are referring to a retail product for lighting control?
