ArduinoAD8232ECG

A python frontend for an arduino AD8232 based ECG. Noise reduction and baseline correction are included to produce plots such as this:

Introduction

  • A quick tour:

  1. Select the COM port the arduino is using. Look in device manager under ports.
  2. This will start/stop monitoring the selected port. This does not record anything. You should see data in (4) if connected correctly.
  3. Starts recording of data. When stop is clicked a prompt will come up to save the data as an excel file. This data has been processed. Try not to record for years I have zero idea how well this copes with large data sets.
  4. Live graph of incoming raw unfiltered data. Yes it looks choppy but is only intended to be a viewfinder and not the final data.
  5. Close the program and kill any serial connection.

Installation

The arduino side

  • Flash the .ino to your arduino. Ensure that all the data pins are correct. These three lines will need changing depending on which pins you decide to use. See wiring diagram below.

This image is stolen (under licence conditions) from the brilliant rescource at https://learn.sparkfun.com/tutorials/ad8232-heart-rate-monitor-hookup-guide/all I would highly reccomend checking this out if you are doing a similar project.

pinMode(10, INPUT); // Setup for leads off detection LO +
pinMode(11, INPUT); // Setup for leads off detection LO -
Serial.println(analogRead(A0));

The python side

  • Anaconda navigator was installed for my setup. Run the .py however you want, in my case I ran it in visual code.
  • A few pakages might need installing. todo I will clean up the code to try to remove unused dependencies.
