    Manuel what kind of piezo do you talk about? Those 'plug and play' or those you MUST produce a tone to hear something?

    For high current, Darlington can be nice in some case, but they usually switch slowly and many have a BIG voltage loss between Collector and Emitter (few volts or so). I prefer MOSFET.

    It's not a bug, it's a random feature.
    There's no problem, only learning opportunities.
