This week we continue the LCD discussion and show you how we got a serial (I2C) interface to an LCD to work. We also show you a graphical display and the start of a new library we are creating for it.

We also, ordered and received since our last show the LCD shield from sainsmart. We show you the simple change you need to make to the sample sketches to get them to work with this shield. Also, how they implemented to buttons to save the number of pins used.
