EDIT: I am using a Mini pro 5v
I have an old lcd display that was laying around here. It is a powertip pc0802a. I hooked it up according to Overview & Parts | DIY 8x2 LCD Shield | Adafruit Learning System using the wiring from the datasheet here. http://www.farnell.com/datasheets/50552.pdf
lcd - YouTube is the issue I am having.
Below is my code. It is the sample code with pins changed and the columns and rows changed.
I added the delay in the loop because at first it was doing some odd flickering. after I added that in I got what is seen in the video.

LiquidCrystal Library - Hello World
Demonstrates the use a 16x2 LCD display. The LiquidCrystal
library works with all LCD displays that are compatible with the
Hitachi HD44780 driver. There are many of them out there, and you
can usually tell them by the 16-pin interface.
This sketch prints "Hello World!" to the LCD
and shows the time.
The circuit:
* LCD RS pin to digital pin 12
* LCD Enable pin to digital pin 11
* LCD D4 pin to digital pin 5
* LCD D5 pin to digital pin 4
* LCD D6 pin to digital pin 3
* LCD D7 pin to digital pin 2
* LCD R/W pin to ground
* LCD VSS pin to ground
* LCD VCC pin to 5V
* 10K resistor:
* ends to +5V and ground
* wiper to LCD VO pin (pin 3)

// include the library code:
#include <LiquidCrystal.h>
// initialize the library with the numbers of the interface pins
LiquidCrystal lcd(11, 12, 7, 8, 9, 10);
void setup() {
// set up the LCD's number of columns and rows:
lcd.begin(8, 2);
// Print a message to the LCD.
lcd.print("hello");
}
void loop() {
// set the cursor to column 0, line 1
// (note: line 1 is the second row, since counting begins with 0):
lcd.setCursor(0, 1);
// print the number of seconds since reset:
delay(500);
lcd.print(millis() / 1000);
