void setup() {

  // In many of the prior examples we saw how Characteristics are initialized when first instantiated.  You can either include an argument:
  //
  //    new Characteristic::Brightness(25);
  //
  // in which case the value of the Brightness Characterisrtic is set to 25 when HomeSpan is powered up, or you can leave the argument blank:
  //
  //    new Characteristic::Brightness();
  //
  // in which case HomeSpan will apply a default value.

  // These methods work fine, with the exception that if the HomeSpan device loses power, it will boot up according to the parameters above rather
  // than remembering the state of each Characteristic after you've made any changes via the Home App or with any PushButtons.

  // In this Example 18 we will see how to instruct HomeSpan to automatically save the values of one or more Characteristics in non-volatile storage
  // so that they can be restored if the power is cycled.

  // To do so, we call the constructor for a Characteristic with TWO arguments as such:
  //
  //    new Characteristic::Brightness(25, true);
  //
  // This instructs HomeSpan to set the Brightness to 25 the very first time the device is powered on, but to SAVE any changes to this Characteristic
  // in NVS, AND RESTORE the last-saved value whenever the power is cycled.  Though HomeSpan takes care of all the saving and restoring automatically for
  // any Characteristic in which you set the second argument of the constructor to be "true," HomeSpan can't automatically perform any needed initialization
  // of the physical appliance by itself.  In other words, HomeSpan can set the value of the Brightness Characteristic to 55 on start-up, if that's the
  // last value used before the power was cycled, but you'll need to add some code to set the brightness of the actual LED at startup.
  
  // To see how this works in practice, we'll configure HomeSpan to operate two Dimmable LEDs, each with its own on/off PushButton.  As usual, all the code
  // is implemented in DEV_LED.h, with comments highlighting all the new features.  See DEV_LED.h for full details.
