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 ...

This module allows the user to wire up an Arduino to any conductive interface (fruits, cans, ect.) and play sounds using that interface. It can be used to create sounds in an integrated system or ...
