// TrueRandomSeed.ino
// This example sketch shows how to provide a truly random seed value to the built in
// library pseudo random number generator. This ensures that your sketch will be
// using a different sequence of random numbers every time it runs. Unlike the
// usually suggested randomSeed(analogRead(0)) this method will provide a much more
// uniform and varied seed value. For more information about the basic technique used
// here to produce a random number or if you need more than one such number you can
// find a library, Entropy from the following web site along with documentation of how
// the library has been tested to provide TRUE random numbers on a variety of AVR
// chips and arduino environments.

//  This is a speed test run on an Arduino Due with an ATSAM3X8E-AU chip dated 1317, it produced the following

//     Starting time test for speed of generation of hardware randrom number gebnrator.
//     It took 262 milliseconds to generato 1,048,576 bytes of entropy!
//  This equates to 4,002,198 bytes per second!
