Pulse sensor to max/msp (or Max4live)

After reading ALL the same threads and questions You posted within last few hours, and having a look at the screenshot,
I would say that You have no idea what arduino sends out on serial port, and also don't know how to read serial port in max.
So where do You want to start solving the problem ?
First learning arduino stuff, so to understand what is going on ?
Somehow I understand why nobody wanted to reply here.
---------
Send info on what You have on Arduino side, and no link to some sites
where one has to go, dig arround and make research abot ongoings.
That's Your job.
If it is clear what aduino is sending, than maybe someone will help You read it in max.

Tnx for the somewhat strong reply. (i feel a bit offended)
yes i posted in a few threads that brought up the issue, and i followed all the info shared on them and similar issues had occurred... time has passed and i am asking if anyone can share info or patch or link to a working set up.
say like in this thread:
https://cycling74.com/forums/pulse-sensor-amped-max
ive tried the pulse sensor arduino files v.1.4 and 1.5 with recommended edits.
ive got the patch on max to work but the data is glitchy and it seems some people managed to get the exact BPM read out, and yes, im lost to how to fix that and would benefit from some guidance.

yes, im a novice but ive made many art+interactive projects through the years and can figure things out pretty well.
this time with the pulse sensor i have very short time to develop the art work and was asking for help from the hive mind.

set up: Arduino UNO board. arduino is loaded with Pulse Sensor Amped 1.5 (also have 1.4 version) with the "true/false" changes. Max has a simple patch for collecting serial info but only getting 255 with glitches. not bpm info

Now I don't own that pulse sensor, and also don't know what Your arduino is sending over serial port.
That's why I asked You to write here what exactly arduino is supossed to send.
Once You know what that is, one can organise a way to read it.
So what is arduino sending, exactly ?
As soon as You provide the details, I will be glad to help as much as I can.

Ok,
arduino is sending serial data and this is what i see in the print window.
(picture attached below)

here is the Arduino code:

/* Pulse Sensor Amped 1.5 by Joel Murphy and Yury Gitman http://www.pulsesensor.com

---------------------- Notes ---------------------- ----------------------
This code:
1) Blinks an LED to User's Live Heartbeat PIN 13
2) Fades an LED to User's Live HeartBeat PIN 5
3) Determines BPM
4) Prints All of the Above to Serial

#define PROCESSING_VISUALIZER 1
#define SERIAL_PLOTTER 2

// Variables
int pulsePin = 0; // Pulse Sensor purple wire connected to analog pin 0
int blinkPin = 13; // pin to blink led at each beat
int fadePin = 5; // pin to do fancy classy fading blink at each beat
int fadeRate = 0; // used to fade LED on with PWM on fadePin

// Volatile Variables, used in the interrupt service routine!
volatile int BPM; // int that holds raw Analog in 0. updated every 2mS
volatile int Signal; // holds the incoming raw data
volatile int IBI = 600; // int that holds the time interval between beats! Must be seeded!
volatile boolean Pulse = false; // "True" when User's live heartbeat is detected. "False" when not a "live beat".
volatile boolean QS = false; // becomes true when Arduoino finds a beat.

// SET THE SERIAL OUTPUT TYPE TO YOUR NEEDS
// PROCESSING_VISUALIZER works with Pulse Sensor Processing Visualizer
// https://github.com/WorldFamousElectronics/PulseSensor_Amped_Processing_Visualizer
// SERIAL_PLOTTER outputs sensor data for viewing with the Arduino Serial Plotter
// run the Serial Plotter at 115200 baud: Tools/Serial Plotter or Command+L
static int outputType = PROCESSING_VISUALIZER;

void setup(){
pinMode(blinkPin,OUTPUT); // pin that will blink to your heartbeat!
pinMode(fadePin,OUTPUT); // pin that will fade to your heartbeat!
Serial.begin(115200); // we agree to talk fast!
interruptSetup(); // sets up to read Pulse Sensor signal every 2mS
// IF YOU ARE POWERING The Pulse Sensor AT VOLTAGE LESS THAN THE BOARD VOLTAGE,
// UN-COMMENT THE NEXT LINE AND APPLY THAT VOLTAGE TO THE A-REF PIN
// analogReference(EXTERNAL);
}

// Where the Magic Happens
void loop(){

serialOutput() ;

if (QS == true){ // A Heartbeat Was Found
// BPM and IBI have been Determined
// Quantified Self "QS" true when arduino finds a heartbeat
fadeRate = 255; // Makes the LED Fade Effect Happen
// Set 'fadeRate' Variable to 255 to fade LED with pulse
serialOutputWhenBeatHappens(); // A Beat Happened, Output that to serial.
QS = false; // reset the Quantified Self flag for next time
}

ledFadeToBeat(); // Makes the LED Fade Effect Happen
delay(20); // take a break
}

void ledFadeToBeat(){
fadeRate -= 15; // set LED fade value
fadeRate = constrain(fadeRate,0,255); // keep LED fade value from going into negative numbers!
analogWrite(fadePin,fadeRate); // fade LED
}

Now that's finaly some more info.
The sketch is over complicated for what it should do, and in first place makes confusion with serial output type selection which is handled by sketch AllSerialHandling.ino.
But now to the thing - You can see from the max serial print that arduino sends a character S followed by reading of the value. (Raw Analog Reading).
When BPM gets calculated from several readings You should also receive BPM followed by the calculated value, and IBI ( time between beats, i guess in ms).
To route the prefix S ( raw analog read) B ( BPM ) and Q (IBI) You must split it before itoa conversion.
You get that errors in max window because change objects is for ints only, not text.
Here is the patch which routes letters S, B and Q to 3 outlets.

And if all You want is BPM value, Arduino sketch can be simplifed, and
that serial handling sketch can be removed.

thank you for the great explanation and patch.

with loading the patch (serial C input is my arduino) its starts reading.
ive check with Print object:
serial outputs = numbers list 10 to 60 range
sel 13 = sends bangs
zl group = sends number lists like "10 83 55 49 55"

But nothing is showing after that.
do i need to change the numbers in the "route" object ?
nothing seems to come past the "route" object.
the second number seems to change according to my heart beat ( 83 changes to a lower number in what seems to be a heart beat)

does the "ASCII Code for S B Q" need to be connected to anything ?

I see , I forgot to add 10 to sel, sorry
I'll upp the patch in a moment

83 is S , so it represents raw analog readings.
66 is B and that is the BPM
81 is Q and that is beat interval in ms I believe
I did not add any smoothing of data, You can do that as You wish.
And the 10 and 13 are ASCII numbers for line feed and carriage return,
so we use 13 as line end to bang zl group to output what's been collected so far.

Brilliant !
its working great.
Thank you so much for helping , my heart rate is lower now :)
ive learned a lot and will dive deeper.

so just for others who might benefit.
with the help of SOURCE AUDIO.
the setup inve got that works:
Arduino Uno board
loaded with
PulseSensorAmped_Arduino_1.5.0
to max msp, with your (SOURCE AUDIO) great patch.
and here with an added simple midi out... ill work on the other configurations on Ableton side soon.
(picture: both BPM and IBI give pulse and BPM could set Ableton project tempo as well)
