Hook everything up EXACTLY like in this picture from the Arduino page:
 
Now load the "Scroll" Example from Arduinos LiquidCrystal Library.
Change these two lines
 
lcd.begin(16, 2);
lcd.setCursor(0,7);
 
to
 
lcd.begin(8, 2);
lcd.setCursor(0,0);
 
now upload it to your Arduino or Seeduino and watch your display fire up!
You may have to adjust the potentiometer a little if you can't see anything.
 
As an alternative to the potentiometer you can connect the Vo pin of the LCD with any available PWM-output (I use pin 9) and add the following code in the setup() section:
 
pinMode(9, OUTPUT);
analogWrite(9, CONTRAST);
 
replace CONTRAST with the value of your choice. Values around 10-20 give a nice bright output.
