Example code:

// Project 12 - Pulse Monitor Test Script


int ledPin = 13;

int sensorPin = 0;


double alpha = 0.75;

int period = 20;

double change = 0.0;


void setup()                  

{

 pinMode(ledPin, OUTPUT);

 Serial.begin(115200);

}


void loop()                    

{

   static double oldValue = 0;

   static double oldChange = 0;

   int rawValue = analogRead(sensorPin);

   double value = alpha * oldValue + (1 - alpha) * rawValue;


   Serial.print(rawValue);

   Serial.print(",");

   Serial.println(value);


   oldValue = value;

   delay(period);
