Voltage triangulation for touch sensing?
I posted here a couple days ago asking about sensing (very broadly) where a touch occurs on a copper plate. I've found this method that uses voltage triangulation, and I got it working on a small 5x5cm piece of ITO (conductive) glass. It doesn't scale well to my 30x35cm copper plate, though. First off, I had to add 100ohm resistors to both grounds or else the Uno I'm using would crash. The voltage values also change across the board instead of changing based on the connected contacts.
