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.

← An Arduino Based Quadruped Robot. The Bicycle Can Tell Us How To Make It Better ... Capacitive touch sensors certainly don’t require a micro. Just an XOR gate will do.

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 ...

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 ...

Capacitive sensing isn't limited to your smartphone. In fact, you can use contact with human skin (or any other conductive surface) to trigger almost any circuit. And the Touch Board from Bare ...
