LCD_PIN1=Arduino_PIN GND
LCD_PIN2=Arduino_PIN 5v
LCD_PIN3=Arduino_PIN GND + add resistors for 
LCD_PIN4=Arduino_PIN 2
LCD_PIN5=Arduino_PIN GND
LCD_PIN6=Arduino_PIN 3
LCD_PIN11=Arduino_PIN 4
LCD_PIN12=Arduino_PIN 5
LCD_PIN13=Arduino_PIN 6

//Example Code 

// include the library code:
#include <LiquidCrystal.h>

// initialize the library with the numbers of the interface pins
LiquidCrystal lcd(2, 3, 4, 5, 6, 7);

void setup() {
  // set up the LCD's number of columns and rows: 
  lcd.begin(16, 2);
  // Print a message to the LCD.
  lcd.print("hello, world!");
}

void loop() {
  // Turn off the blinking cursor:
  lcd.noBlink();
  delay(3000);
   // Turn on the blinking cursor:
  lcd.blink();
  delay(3000);
}
