    * The Arduino random number generator is seeded with a random value
-   * derrived from entropy from the temperature, voltage reading, and
-   * microseconds since boot.
+   * derived from entropy from an ADC reading of a floating pin combined with

    * This method is still most effective when called after a semi-random time,
