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.

And the Touch Board from Bare Conductive wants you to combine your DIY spirit with the ability to turn practically any surface into a sensor. At the heart is an Arduino compatible microcontroller ...

Of all the Arduino projects we've seen 'round here, this is certainly one of them! Using nothing but a Graphics LCD, an Arduino, and a WebSocket server he wrote using Python / Tornado, this young ...

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 ...

Some of this light is directed down into the screen, towards an array of 64 IR sensors. By scanning through the sensors, you can determine the x and y position of the touch event(s) and use this ...
