An Arduino can measure time, a coil and a resistor will create a delay proportional to the circuit values, and metal around the coil will change the coil’s inductance.

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.

A new Instructables page has been created to make an eco-friendly DIY metal detector using an Arduino Mega just been combined with a 3.2 inch TFT LCD touchscreen to provide a fantastic readout ...

At the heart is an Arduino compatible microcontroller (based on the Leonardo) with a few extras baked in, including a Freescale touch sensor connected to 12 electrodes and an audio processor for ...

Building on its Embedded Video Engine (EVE) technology FTDI Chip is introducing a series of Arduino-compatible development platforms. The VM800P series (where P signifies PLUS) gives engineers ...

Using the power of Arduino, Evan Kale has ingeniously transformed a weed wacker into an Arduino-powered metal detector. This innovative project showcases the versatility and potential of Arduino ...

Not a lot to say about this little hack but it's basically a Game Boy Advance attached to an Arduino device running a touchscreen. The stylus sends data back to the Arduino which connects to the ...
