The sensor forms an image and OpenCV detects the actual touch configuration. It appears you can use the raw data from the Arduino, too, but it might be a little harder.

This tutorial will guide you through the process of building a tachometer around an Arduino. Tachometers are used to measure rotation rate in Revolutions Per Minute (RPM). You don’t need much… ...

In a world increasingly dominated by touchscreens, a London design studio is taking an approach to touch that's both low(er)-tech and innovative at the same time. Bare Conductive raised over US ...
