/* reads a sensor on pin A0 and sends raw and smoothed values via serial, comma-separated.
   Sends COMMA-SEPARATED values in the range 0 to 1023, followed by a newline, or newline and carriage return.
   Use with "graphMultiple" processing code

/* Sensor smoothing
   by Eric Forman [www.ericforman.com]
   Original version 2008, updated May 2012

   Smooths sensor readings by adding only a fraction of new values.
   The more the new value is divided, the smaller the change, thus a smoother result
   As with any smoothing function, the more you smooth, the slower the response time
