This repo contains an Arduino program to calculate heart rate from the analog signal of a Vernier hand grip sensor.
This is part of the final project of the Electronic Devices for Biomedical Design course (HCMIU VNU-HCMC, Sep 2020 - Jan 2021).
Tutorial at https://www.vernier.com/engineering/arduino/arduino-online-guide/connecting-vernier-sensors-to-arduino/
- Take analog input from the Vernier sensor
- Detect peaks
- Calculate heart rate (is the mean period between each peak) with filtering and dampening to smoothen results
- Output heart rate
