-/* ATSHA204 Library Simple Example
-   by: Jim Lindblom
-   SparkFun Electronics
-   date: November 8, 2012
-   
-   This code shows how to wake up and verify that an SHA204 is
-   connected and operational. And how to obtain an SHA204's unique serial
-   number, and send it a MAC challenge.
-   
-   The ATSHA204's SDA pin can be connected to any of the Arduino's digital pins.
-   When constructing your atsha204Class, pass the constructor the pin you want to use.
-   In this example we'll attach SDA to pin 7.
-   
-   The ATSHA204 can be powered between 3.3V and 5V.
