node library for the pulsesensor, designed to interact with [tessel] the [pulsesensor] pulsesensor.com) is an open source pulse sensor. it shines green light through your skin, then reads the intensity of light back. this light intensity changes based on the action in your capillaries, so the analog value read back correlates with your pulse. put the heart side of the pulsesensor to your fingertip, then wrap it securely with the provided velcro strip. you should feel your pulse in your fingertip. it would be a good idea to also peruse [this pdf] from the manufacturers, which shows you how to seal and

QUESTION
I am new in developing Arduino and I encounter bugs already. I have searched in the internet but still no luck.
The situation is, I have an ESP32 Dev Kit with 32 pins and I have this PulseSensor from pulsesensor.com. I tried the example Getting_BPM_to_Monitor in the PulseSensorPlayground Library and encountered problems.
The problem is in the void setup function pulsesensor can not create a object here.
My code:
...ANSWER
Answered 2019-Dec-22 at 14:25I never use PulseSensor so I don't know whether it supports ESP32 or not. But I think your code is directly copy form Arduino and try to run it on ESP32.
How exactly you connect the PulseSensor to ESP32? i.e. Which pin the pulse sensor is connected to ESP32?
In Arduino, const int PulseWire = 0;
which you used for analogRead make sense as it is referring to A0, but for ESP32 Arduino Core, ADC0 is at GPIO36 (see ESP32 Arduino Core pinmap, it will simply not work.
In order to connect the analog sensor to ESP32 ADC0, you will need to define the PulseWire as 36.
QUESTION
tldr; what is an easy/logical way (for a beginner) to calculate BPM using pulse sensor and mkr1000? I don't want any visualizations or processing sketch, but just print BPM values
Please bear with me, I am a newbie at this and i've tried my best to understand this and fix this issue, but in vain.
I am using the pulse sensor (SEN-11574) with Arduino mkr1000 to calculate the BPM and print it in serial monitor. I was able to get raw readings using their starter code
