/*
  LiquidCrystal Library - Test ASI
  Gebruikt als demo verschillede LCD stuff op een Arduino MEGA 2560
  
  The circuit:
  LCD VSS pin(1) to ground
  LCD VCC pin(2) to 5V
  LCD VO  pin(3) pot.meter set to 0.7V
  LCD RS  pin(4) to digital Arduino header pin 41
  LCD RW  pin(5) to digital Arduino header pin 40
  LCD EN  pin(6) to digital Arduino header pin 39
  
             LCD: DB0  to  DB7
         LCD pin: 7    to  14
  Arduino header: 49   to  42
       uC port L: 0    to  7
