 LCD2004  MESSAGE 
 this project is showing how to display information on lcd (20,4)
 also inclide chasing led code 2
THERE ARE THREE STAGES OF CODING 
1 DEFINES/INCLUDE LIABRARIES
2 VOIDE SETUP
3 VOIDE LOOP
TREATTHE BIG CODE AS CODE ONE CPOY AND PAST THE RESPECTIVE STAGES OF CODE 2 TO CODE ONE 
CONECTS THE HARDWARE

ORIGINAL CODE
