I'm trying to make a pressure sensor matrix. The usual way to do so is by rows and cols of conductive thread on conductive/neoprene fabric and velostat in between. That way though I have to use many inputs, which is something I don't like.
So I stumble upon the charlieplexing pattern. Here's an example ( http://www.flickr.com/photos/missioncontrol/3767663436/in/set-72157621761527159/
The think is I don't really understand how to read the values from it. If the top left corner of a charlieplexing pattern is pressed, it returns deferent value from lets say the bottom left corner? What happens in we press further towards the inside of the pattern?
Seems really interesting but I could find any info on the subject. Not even a paper.
Any help would be greatly appreciated. Thank you. And thank you for being an awesome community
