LCD print by BARRAGAN
Demonstrates the use of a generic text liquid crystal dsplay (LCD) to print the value of a variable

    #include <LiquidCrystal.h>

    // creates a LiquidDisplay object with R/S, R/W and E on pins 8,9,10 and
    // data pins on port 2
    LiquidCrystal myDisplay = LiquidCrystal(5,6,7,1);

    void setup()
    {
      // nothing for setup
    }

    int a = 0;

    void loop()
    {
      myDisplay.clear();
      myDisplay.home();
      myDisplay.print("Variable a is: ");
      myDisplay.setCursor(16, 0);
      myDisplay.print(a);
      a = a + 1;
      delay(200);
