Heartbeat Sensor Projects with PulseSensor

Bring live heartbeats and heart rate data into your electronics projects as an impressive feature that builds user engagement. If you’re a Maker, developer, or artist, you’ve probably run into common, frustrating stumbling blocks for incorporating bio-sensors. Get the upper hand on smoothly integrating heartbeats into your projects on any platform with PulseSensor.

First, you'll explore working with PulseSensor with a simple battery, LED, and speaker. Then deepen your knowledge by going through achievable projects using Arduino, nRF52, mico:bit, and other prototyping platforms. This book will guide you through hooking up the PulseSensor to circuits with motors, a GUI, and even the cloud.

You’ll get practical tips and tricks that work in the lab, field, and even at public events, and look at the advantages of using PulseSensor on one electronics platform vs. another. You'll also look at the best ways to get a reliable heartbeat and BPM readings from different users in different applications. Finally, this book will show you the easiest path to put heartbeats into your prototypes, whether creating a new generation of hardware or making a memorable cosplay costume.

WHAT YOU'LL LEARN

* Work with PulseSensor directly on a breadboard with AA batteries and LEDs


* Get up and running with PulseSensor on Arduino, micro:bit, and nRF52


* Anticipate and address common bio-sensing issues that slow down prototyping


* Explore future applications like BPM tracking on the Arduino IoT Cloud

WHO THIS BOOK IS FOR

Makers from hobbyists to engineers to students who would like to incorporate cardiac biofeedback into their projects. JOEL MURPHY (BFA MassArt, Boston; MFA UC San Diego) is a creative technologist living in Brooklyn. He owns Flywheel Lab, a business designing and fabricating electro-mechanical projects for artists and designers. He taught Physical Computing at Parsons from 2006 to 2014. He’s also the co-founder of OpenBCI.

YURY GITMAN (BS GaTech, Atlanta; MPS ITP NYU, NYC) has taught physical computing, toy design, and mobile app development in the Design and Technology program at the Parsons School of Design since 2003. Yury is also the co-founder of PulseSensor.com, which makes and distributes a popular and easy-to-use heartbeat sensor. With a background in toy design, he often plays with his kids' toys more than they do.
