    This is a Tutorial of how to do Pulse/ Heartbeat Rate (BPM) Measurement using Arduino :

    In this article, we are going to interface a Pulse Sensor with Arduino. The pulse sensor we are going to use is a plug and play heart rate sensor. This sensor is quite easy to use and operate. Place your finger on top of the sensor and it will sense the heartbeat by measuring the change in light from the expansion of capillary blood vessels. When a heartbeat occurs blood is pumped through the human body and gets squeezed into the capillary tissues. The volume of these capillary tissues increases as a result of the heartbeat. But in between the heartbeats (the time between two consecutive heartbeats,) this volume inside capillary tissues decreases. This change in volume between the heartbeats affects the amount of light that will transmit through these tissues. This change is very small but we can measure it with the help of Arduino.




    Heartbeat/Pulse/BPM Rate Monitor using Arduino & Pulse Sensor

    const int LED13 = 13;          // The on-board Arduino LED, close to PIN 13.
    int Threshold = 550;           // Determine which Signal to "count as a beat" and which to ignore.
                                   // Use the "Gettting Started Project" to fine-tune Threshold Value beyond default setting.
                                   // Otherwise leave the default "550" value.

     int myBPM = pulseSensor.getBeatsPerMinute();  // Calls function on our pulseSensor object that returns BPM as an "int".
                                                   // "myBPM" hold this BPM value now. 
    
    if (pulseSensor.sawStartOfBeat()) {            // Constantly test to see if "a beat happened". 
     Serial.println("♥  A HeartBeat Happened ! "); // If test is "true", print a message "a heartbeat happened".
     Serial.print("BPM: ");                        // Print phrase "BPM: "
