1) This shows a live human Heartbeat Pulse.
2) Live visualization in Arduino's Cool "Serial Plotter".
3) Blink an LED on each Heartbeat.
4) This is the direct Pulse Sensor's Signal.
5) A great first-step in troubleshooting your circuit and connections.
6) "Human-readable" code that is newbie friendly."

// Variables
int PulseSensorPurplePin = 0; // Pulse Sensor PURPLE WIRE connected to ANALOG PIN 0
int LED13 = 13; // The on-board Arduion LED
int Signal; // holds the incoming raw data. Signal value can range from 0-1024
int Threshold = 550; // Determine which Signal to "count as a beat", and which to ingore.
// The SetUp Function:
void setup() {
pinMode(LED13,OUTPUT); // pin that will blink to your heartbeat!
Serial.begin(9600); // Set's up Serial Communication at certain speed.
}
// The Main Loop Function
void loop() {
Signal = analogRead(PulseSensorPurplePin); // Read the PulseSensor's value.
// Assign this value to the "Signal" variable.
Serial.println(Signal); // Send the Signal value to Serial Plotter.
if(Signal > Threshold){ // If the signal is above "550", then "turn-on" Arduino's on-Board LED.
digitalWrite(LED13,HIGH);
} else {
digitalWrite(LED13,LOW); // Else, the sigal must be below "550", so "turn-off" this LED.

The gsr code
The gsr code:
void setup()
{
Serial.begin(9600);
pinMode(2, OUTPUT);
pinMode(3, OUTPUT);
pinMode(4, OUTPUT);
digitalWrite(2, HIGH);
delay(500);
digitalWrite(3, HIGH);
delay(500);
digitalWrite(4, HIGH);
delay(500);
}
void loop()
{
if (analogRead(A0) > 60)
{
digitalWrite(4, HIGH);
}
else
{
digitalWrite(4, LOW);
}
if (analogRead(A0) > 20)
{
digitalWrite(2, HIGH);
}
else
{
digitalWrite(2, LOW);
}
if (analogRead(A0) > 45)
{
digitalWrite(3, HIGH);
}
else
{
digitalWrite(3, LOW);
}
Serial.println(analogRead(A0));
delay(20);
