Arduino Heart Rate Analysis Toolkit

This repository contains Arduino IDE implementations of the Python Heart Rate Analysis Toolkit.

Several sketches are available for various AVR (e.g. Arduino) and ARM (e.g. Teensy) chipsets. All implementations have a USB-mode for use in connection with a computer, and an SD-mode that utilised SD-cards to store the data. Suggested wiring diagrams are available for all versions. See the links below for examples of each.

Note, reports of SD logging interrupting and/or dropping samples have made me move them to "Experimental". I will expect to implement a fix for this within a few weeks.
