Simple one variable Kalman filter library for Arduino
Import 'KalmanFilter' directory as Arduino library:
Arduino.app -> Sketch -> Import Library... -> Add Library
Initialize filter:
#include "KalmanFilter.h"
KalmanFilter filter; // create with default parameters
filter.setState( defaultValue ); // setup vith default value
And use:
double value = getValueFromSensor();
filter.correct( value ); // add new value from sensor
double correctedValue = filter.getState(); // get corrected value
