What Happens When You Combine VR With Biofeedback? #WearableWednesday #wearabletech #VR #art

Virtual Reality helps to create an immersive experience, but this project by Chelly Jin brings another level by adding heart rate. Here’s her description of the project Solitude: Biofeedback Virtual Reality.

This piece re-conceptualizes loneliness into solitude by developing a unique body and sensory awareness. Users become aware of their solitude, but in return experience a ‘world’ influenced by their state of being and breathing.

An Arduino and pulse sensor are the additions to the Oculus Rift adding the depth of experience. Images were created using the Unity Game Engine and it’s fascinating to watch the planets change size in response to the sensor. For people that cannot do meditation, this setup may prove to be relaxing and help to focus attention on the breath. I could also see this being used in cases where people are experiencing stress, such as in a hospital waiting room. Chelly is a student at University of California Los Angeles and I encourage you to take a peek at her portfolio, which is quickly growing. For those of you who are contemplating heart rate for a future project, you should definitely check out our learning guide for the Meditation Trainer. It uses a Pulse Sensor Amped with our easy-to-use Circuit Playground Microcontroller to help you visualize your Heart Rate Variability (HRV). The bottom LEDs give you the color representing your state of relaxation while LEDs on the upper part of the microcontroller help pace your breathing. So, learn about the pulse sensor and its code in a practical way that will help you deal with stress better.

Flora breadboard is Every Wednesday is Wearable Wednesday here at Adafruit! We’re bringing you the blinkiest, most fashionable, innovative, and useful wearables from around the web and in our own original projects featuring our wearable Arduino-compatible platform, FLORA. Be sure to post up your wearables projects in the forums or send us a link and you might be featured here on Wearable Wednesday!


As 2022 starts, let’s take some time to share our goals for CircuitPython in 2022. Just like past years (full summary 2019, 2020, and 2021), we’d like everyone in the CircuitPython community to contribute by posting their thoughts to some public place on the Internet. Here are a few ways to post: a video on YouTub, a post on the CircuitPython forum, a blog post on your site, a series of Tweets, a Gist on GitHub. We want to hear from you. When you post, please add #CircuitPython2022 and email circuitpython2022@adafruit.com to let us know about your post so we can blog it up here.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
