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. We imagine aluminum foil ...

The sensor shown here is essentially two plates mounted side-by-side, attached to an Arduino Nano using the Capacitor library which uses just two pins, one digital and one analog.

The Touch Board is based around an Arduino Leonardo board that also sports an MP3 player / MIDI device, a MicroSD card socket, 3.5 mm audio jack and what Johnson described as the "secret sauce ...

Another day, another Arduino project. This time it's something called SuperDuino, a tiny touchscreen powered by a coin cell battery and backed up by a tiny Arduino-Like processor. The kit can be ...
