A small, tactile-free binary calculator built using an HW-138 capacitive touch sensor (TTP2xx-family style capacitive touch breakout) and an Arduino Uno. The project reads touch inputs and interprets ...

You don’t have to have high-quality parts to play around with electronics and here’s a great example. [Vishal] used junk to play around with CapSense, the touch sensitive Arduino library. What he ...

Capacitive touch sensors are entirely in the domain of DIY, requiring little more than a carefully-chosen conductive surface and a microcontroller. This led [John Phillips] to ask why not embed such ...
