An Arduino Uno metal touch sensor module detects touch through metal surfaces. It senses capacitance changes when touched, allowing for touch-based controls and user interfaces in various electroni ...

Instead of using mechanical paddles, [Sebastian] brought his iambic key into the 21st century by using a touch sensor. An ATtiny45 measures the time it takes for a single metal plate to fully charge.

The sensor shown here is essentially two plates mounted side-by-side, attached to an Arduino Nano using the Capacitor library which uses just two pins, one digital and one analog.

The Arduino Nano metal touch sensor module detects touch or proximity to conductive objects, triggering an output signal. It's commonly used for touch-sensitive interfaces, proximity detection, and ...
