  Now I have connected Pin analog 4 (SDA ) and analog 5 (SDL) to the resepective Two wire interface for the board on the back of the 20 x 4 LCD as well as VCC and GND.
  How do I know which address to use as well? I have seen a lot of 0x27 stuff
  .i read how someone wrote you have to also code wire.begin but that just shows an error.
  I was wondering myself what wire.begin
  ?How do I know which address to use as well? I have seen a lot of 0x27 stuffI was using the LiquidCrystal_I2C lcd( 0x27, 20, 4); to initiate the LCD...
  how do I "open the serial monitor"
  This is a dumb question, I know...but how do I "open the serial monitor" I uploaded the code for the I2C scanner and it compiled fine...but now what? I did try the new liquid crystal library but which version are you referring to? There are like 10 downloads on that bitbucket page.....so confusing....and is this for 1.0 or 1.0.1? I saw some posts of some sainsmarts getting to work, but dammit I want mine to
  To install the library:* Download the most recent version of the library....
  == Version ==Current New LiquidCrystal is the latest zip file in the download section.The New LiquidCrystal library has been tested and is compatible with Arduino SDK 1.0.1, 1.0 and Arduino SDK 0022.
