6 years ago Here is a comparison: Figure 1 is for a 74 year old male. HRV is very low.
Figure 2 is for a 20 year old male, breathing normally.
Figure 3 is the same guy breathing at 6 breaths per minute. Note how HRV goes up, from 4 to 22.

6 years ago Hey @georod99 that's really cool! Something is wacky with the font sizes on your screenshots. Did you change that in the sketch?

commented
6 years ago No, since the beginning I was wondering exactly that, how you did not use a smaller font.

Thanks.

6 years ago Hi George,
I'm just running the code on my machine, and I get the font size shown below. In the github, the font that is loaded into the data file is Arial-BoldMT-36.vlw
If you want to change the font, in Processing, go to Tools > Create Font... to pick a different size. This process will load the font into the data folder so the sketch can use it. I'm going to download the latest Processing to see if that makes any difference at all.
Also, in the sketch, you can change the font size with the line
textFont(font,12);
where the second parameter is the font size you want to use. It's always better to load a larger font and then adjust to smaller font when you want, and not the other way around.
Try re-downloading the code?

6 years ago /* PulseSensor Amped HRV Biofeedback v1.1.0
This is an HRV visualizer code for Pulse Sensor. www.pulsesensor.com Use this with PulseSensor_BPM Arduino code and the Pulse Sensor Amped hardware. This code will track Heart Rate Variabilty by tracing the changes in BPM values The code looks for a change in the trend of BPM values, up or down, and calculates the HRV using the last peak or trough. HRV, measured in the difference in BPM is also graphed. There is also a breathing prompt that helps you breath at a specific breaths per minute.

(JPG image saved in Sketch folder) press 'C' to refresh the graph press 'W' to show or hide the IBI waveform (as seen in Time Domain example) Created by Joel Murphy, Spring 2018 Updated Summer 2013 for efficiency and readability This code released into the public domain without promises that it will work for your intended application.

6 years ago I'm new to Arduino and Processing. I have studied the parts that I need, but I will never study the whole language. If somebody wants to explain (comment) the following lines (in the former sketch): 23 and 24: how can I change the font size. 92 font = loadFont("Arial-BoldMT-18.vlw"); 93 textFont(font); 196 text("BPM: "+int(BPM), pulseX,50); 265 text(i, 40,map(i,30,150,615,75)); 272 ine(75,map(i,30,150,614,74),85,map(i,30,150,614,74)); and in general, the lines that contain "text", so I can customize the graphic. I will appreciate the help.
Building off the Frequency Domain sketch. This HRV Biofeedback sketch provides a breathing prompt, graph of BPM over time, and graph of HRV, the difference in the highest and lowest BPM.
