Hello everybody,
I am trying to use incoming sound signal (amplitude) to drive intesity of solenoid. I have asked here before and was recommended this arduino 0 - 5V handicap bypass but I could not understand how to get the amplitude or why trying to bypass the limitations when on some other tutorials the VU meter works just fine.
Can somebody help me understand whats the difference?
What I am trying to do is, if for example I have a droning pulsing sound the electromagnet would be "pulsing" as well. With the first mentioned tutorial I wasnt able to understand how to get the amplitude and how to drive the solenoid with it. The other tutorial seems a lot simplier but there might by a catch.
Thank you so much for your answers.
