I searched but the forum for an answer but I could not find it, sorry if this is another topic about the same question...
From what I understand MD detects a voltage from a piezo between an input and ground. Since a switch does not produce a voltage like a piezo, I imagine something more complicated is needed to connect only a simple push button to an input and have it detect a push on the button.
Can someone advice me with a wiring diagram? Thanks in advance.
