I am a newbie in the world of circuits and electronics. But we all started somewhere.
I have this idea about a street sign that should be used as an instrument. All most like a Theremin. Touching it high gives a high note, and touching it low, low note.
So is there a way that I could measure where on the steel rod/sign I am touching it? I have been surfing around for awhile, and I came up with something like a comparison of a capacitor in each end of the rod/sign.
So, am I totally off, or is there a smarter way to do this?
