How do I STOP the execution PulseSensor sequence?

Data interpretation

I was just wondering if I could get some assistance or suggestions as to how to determine the actual BPM from the output data. I made and excel graph (Frequency vs Time)--- where I am not sure if the increments in time are in milliseconds or something else. Keeping in mind that the threshold is maintained at 550, and with the data obtained, I seem to be getting numbers around 250 BPM (while a person is at rest). For example, the time difference between areas that surpass the 550 threshold is as such: t(2) = 401, t(1) = 378; t(2)-t(1) = 23 milliseconds which translates to 0.00038 (min)--- and so 1/.00038 = 2600 BPM??
I may just be misinterpreting the data and would greatly appreciate some help.
Thank you

Can arduino nano be used? Sketch size too high.

I'm using an Arduino nano and having following problem. So far i can see Arduino uno and nano has the same SRAM of 2 KB. Is the problem really that I'm using a Arduino nano?

"Build options changed, rebuilding all
Sketch uses 2250 bytes (15%) of program storage space. Maximum is 14336 bytes.
Global variables use 190 bytes (18%) of dynamic memory, leaving 834 bytes for local variables. Maximum is 1024 bytes.
avrdude: ser_open(): can't open device "COM1": No such file or directory
Problem uploading to board. See http://www.arduino.cc/en/Guide/Troubleshooting#upload for suggestions."

I have a WEMOS D1R1 that runs on 12 Mhz clock oscillator

I did change the code as showed in Time_Interrupt_Notes.ino but the pulse rate is reading too fastly.
What can I do to make it slower or can I use some kind of hardware Timer like in Arduino?
The code runs perfectly on my Arduino mega but I need to run it on wemos D1R1 because it has ESP8266 module implemented and after that I want to get the data on a webpage.

Arduino nano rp2040 connect troubleshooting

Hello, first thank you for your work on PulseSensor, it is a great tool. I first tried it with an arduino uno on a previous project, and everything went smoothly. However now that I've got a nano rp2040, the sketches won't compile (including the examples provided with the library). I get a bunch or errors, and looking at them I feel a bit out of my depth. Could you please help me figure it out ?

Pulse Sensor giving unexpected readings based on examples

Hello,

I appear to be coming across an issue using the pulse sensor shown in this repository and the library doesn't seem to clear things up for me. I have tried reading my pulse sensor using the visualiser but get very noisy readings with very low amplitude.

The code I have employed is the following, but I have also tried running through the PulsePlayground library and am obtaining the same results:
`
#include <Adafruit_GFX.h>
#include <UTFTGLUE.h>
UTFTGLUE myGLCD(0x9488, A2, A1, A3, A4, A0);

// Declare which fonts we will be using
#if !defined(SmallFont)
extern uint8_t SmallFont[]; //.kbv GLUE defines as GFXFont ref
#endif

#define UpperThreshold 516
#define LowerThreshold 515

void setup() {
Serial.begin(9600);
pinMode(A0, OUTPUT); //.kbv mcufriend have RD on A0
digitalWrite(A0, HIGH);
// Setup the LCD
myGLCD.InitLCD();
myGLCD.setFont(SmallFont);
// Clear the screen and draw the frame
myGLCD.clrScr();
// BPM Parameters
myGLCD.setColor(255, 255, 255);
myGLCD.print(" BPM", 5, 34);
}

void loop() {

int LastTime = 0;
bool BPMTiming = false;
bool BeatComplete = false;
int BPM = 0;

static unsigned long lastTime = 0;
const unsigned long INTERVAL = 20; //milliseconds, calculated as 1 divided by sample frequency
while (millis() - lastTime < INTERVAL)
{
//wait; do nothing until the sample interval expires
}
lastTime = millis();

// Calculate when a beat has been completed
if (analogRead(A5) > UpperThreshold)
{
if (BeatComplete == true)
{
BPM = millis() - LastTime;
BPM = int(60 / (float(BPM) / 1000));
BPMTiming = false;
BeatComplete = false;
}
if (BPMTiming == false)
{
LastTime = millis();
BPMTiming = true;
}
}

if ((analogRead(A5) < LowerThreshold) & (BPMTiming))
{
BeatComplete = true;
}

Serial.println(analogRead(A5)); //Plots the readings in the serial plotter

// Display BPM when calculated at the bottom of the loop
myGLCD.setColor(255, 255, 255);
myGLCD.printNumI(BPM, 40, 34);
}
`

I have attached an image of the readings I'm getting and am hoping you might be able to give me an insight into the reason for the difference. The image on the left is from: https://pulsesensor.com/pages/pulse-sensor-amped-arduino-v1dot1

Error compiling for board Arduino Uno WiFi Rev2.`_

Library not working for Arduino Uno WiFi Rev2.

It seems the code can't be compiled for the Arduino Uno WiFi Rev2. Is there a simple fix for this issue? Or do I need to use a regular Arduino Uno?

This is the error I got:

Incompatibility with SSD1306 Libraries

The library does not seem to work with Adafruits SSD1306 Lib and causes init errors. I have removed the SD library and it still gives the same issue, it only seems to be a combo of the two libs causing the issue

Can I run on Arduino 101?

...

I already have a version of this patented

I am working on creating a full program for the Heart Synth Monitor I have created and Patented. Nice try to be sneaky and basic but, this design is currently being developed by me and I don’t appreciate you not contacting me before trying to market your altered development.

I somehow can't get any good data

Hi

After connecting the heartbeat sensor, I'm now trying to get data from it. However, it just spikes a bit, not even looking like a beating heart. The sensor lights up green so it is connected..
Any tips?

safety

Hi,
can anyone tell me if Heart Rate sensors are electrical isolated from the Arduino power supply or is a battery power supply required

Why it says 600 bpm is ir because the sensor is amped?

How can i know what bpm i habe when it says 500-600bpm? Can you help pls. Would divide the display out do the job?

PulseSensor-RaspberryPi - BPM 3-times too high?

Dear team,

first of all my appreciation for what you are doing here with the PulseSensor and the code you are providing!

My setup includes a RaspberryPi 3b and I have the MCP3008 ADC sitting in between the sensor and my SPI port (8).
Everything is working fine, beside the fact, that my BPM appears approximately 3 times higher than in reality (I measured it with a commercial product).
I am providing a sample output below.

Any idea what the root cause of this might can be ?

Best
Thomas

MKRZERO not compiling

Hi,
I'm using an arduino MKRZERO but it doesn't want to compile the PulseSensor_BPM or PulseSensor_BPM_Alternative examples. It seems to be complaining about interrupts. The USE_ARDUINO_INTERRUPTS is true for the PulseSensor_BPM and false for the PulseSensor_BPM_Alternative. I was wondering if i had to modify anything else?
Thank you.
