Hey there,
I'm trying to work through a project that would let me control the voltage of an incandescent lamp through a peizo transducer. In other words, the more vibration the peizo picks up the brighter the lamp will be. Was hoping someone here might be able to start me in the right direction.
After doing some research, I was able to find this kit here:

I think this might be what I need, but I'm not sure how I'm going to get the peizo to control the 10Vdc analog input. Though, I could be barking up the wrong tree. there might be a more simpler solution than that circuit kit. I'm not married to the idea of using that kit, was just the first step I found that might help me.
I thought about using a relay or switch of some kind but I don't think that would allow for smooth dimming of the light. The light needs to directly respond with brightness according to the peizo sensor's voltage output. The peizo will be attached to the sound board of a piano that will be striking long decaying chords and ideally the light would gradually leave as the sound softens.
I hope all of this makes sense, and thanks ahead of time.
