This article can be more of a guide on how to construct an heartbeat sensor utilizing an Arduino. Although a complicated one, this project comes as an interesting one to many electronics hobbyists.

There are many ways to detect a heartbeat electronically. One of the simpler ways is to take [Orlando’s] approach. He’s built a finger-mounted pulse detector using a few simple components and an ...

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 ...
