+  Hotboards_rtcc Library - setting time and date with compiler macros
+ Demonstrates the use a MCP7941x clock calendar.  
+ The Hotboards_rtcc library works with this microchip real time clock
+ (http://www.hotboards.org).
+ 
+ This sketch set time and date using compiler macros, and then send through 
+ serial port every five seconds
+  The circuit:
+ *  VDD  -->  3.3v
+ *  GND  -->  GND
+ *  SDA  -->  SDA
+ *  SCL  -->  SCL
