A simple AVR microcontroller based circuit that can detect when you touch a metal probe connected to one of the mcu inputs. A simple AVR microcontroller based circuit that can detect when you touch a ...

Creating capacitive touch-sensitive buttons is easy these days; many microcontrollers have cap-sense hardware built-in. This will work for simple on/off control, but what if you want a linear, ...

We're used to touchscreens, but now researchers have created new, touch-sensitive fibers that can be used to interact with electronic devices. The microscopic fibers are soft, stretchable and capable ...

Infineon has augmented touch sensing and liquid level sensing it a new series of MCUs. Devices in the 4000T family have hardware and software to implement: enhanced capacitive touch sensing, inductive ...

You can’t have a touch sensitive switch without a way to detect the presence of a finger! A touch sensor, especially a capacitive touch sensor, has some surprisingly sophisticated electronics to ...

[mircemk] shows how to create a simple non-contact proximity sensor using little more than an Arduino Nano board, and a convenient software library intended to measure the value of capacitors. The ...

• Trapped acoustic resonance is most simply described with an analogy: the ringing of a bell. • Microprocessors control the frequency of the mechanical resonance and monitors its decay. • A thicker ...

Researchers at the MIT Media Lab and the Max Planck Institutes have created a foldable, cuttable multi-touch sensor that works no matter how you cut it, allowing multi-touch input on nearly any ...
