Capacitive touch sensing allows for triggering the sensor without actually physically touching one’s lips to the electrodes, which [Nathan] did by putting a clear plastic layer over the PCB traces.

Inside the sleeve is an MPRP121 capacitive touch sensor and an Arduino that controls the LEDs and sends the signals to a Raspberry Pi hidden among the ruffles in the back of the dress.

A simple, beginner-friendly C++ library that brings capacitive touch sensing to the Arduino UNO‑R4 Minima and UNO‑R4 WiFi. It abstracts away all the low‑level CTSU, DTC, and interrupt details so you ...

I am trying to test a capacitive touch sensor. Specifically, I want to show that it registers a specific change in capacitance. Capacitance is defined as: C = A * Eo * Er / d Keeping A, Eo and d ...

Capacitive sensors are able to detect when they are touched without requiring a pressure or movement. Even with AirPods Pro, it's possible to knock them out of your ear so anything that stops you ...
