Sample Code:
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);
}
