There are 2 repositories under biofeedback topic.
A PulseSensor library (for Arduino) that collects our most popular projects in one place.
Heart rate variability (HRV) biofeedback with Polar ECG chest straps.
real-time neuro-/biosignal processing and streaming pipeline
PhysioKit: Open-source, accessible Physiological Computing Toolkit
OUTDATED, FIND MY ESP32 REPO AT https://github.com/moothyknight/HEG_ESP32 -- A DIY instruction set and rough program to run an HEG off an Arduino Nano. It uses an IR and Red LED, an OPT101 sensor, an ADS1115, and an Arduino Nano V3. The HEG is basically a pulse oximeter for your cortex, but allows for biofeedback and direct control.
A plug-and-play MATLAB based tool to use NES games for multimodal biofeedback.
Hackathon project: ADHD treatment using real-time brainwave biofeedback.
The long way from K.G.Jung to contemporary polygraphists. The progress is evident, but maybe something important and essential is lost? Let's try to be clear and sort things out with Arduino. "Aha, a looking glass into the unconscious!" - Carl Jung If you have interest, Arduino board, some cheap components, patience to understand several simple but fundamental regularities, then you have the opportunity to have at your disposal no less impressive equipment and method, as Jung had. THE STORY IS ABOUT SERIOUS LOOK TO ELECTRODERMAL ACTIVITY OF HUMAN SKIN – THE MOST POPULAR PSYCHOPHYSIOLOGICAL REACTION DURING MORE THAN 100 YEARS.
An experimental compact system for doing game-based EEG biofeedback using an OpenBCI data stream over UDP. A control component receives and processes EEG data and calculates a reward value based on configurable thresholds. A feedback component provides real-time audiovisual feedback and scoring to the neurofeedback user wearing the BCI headgear.
