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, ...

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 ...

Capacitive touch buttons are a great way to turn just about any (non-conductive) surface into a button, but people generally dislike the lack of tactile feedback. [KontinuumLab] apparently agreed and ...
