eeprom_get example.

+
This shows how to use the EEPROM.get() method.
-
+
To pre-set the EEPROM data, run the example sketch eeprom_put.
- This sketch will run without it, however, the values shown
+ This sketch will run without it, however, the values shown
will be shown from what ever is already on the EEPROM.
-
+
This may cause the serial object to print out a large string
of garbage if there is no null character inside one of the strings
loaded.
