Very basic interface with Arduino and LCD screen

This is a little something I started working with this week.
I bought a Serial LCD screen from Sparkfun last year and I just realized that I have never used it.

This is as basic as it gets. Two buttons for cycling through the options and one button for action.

The next step is adding PWM and controlling it with another two buttons and maybe a setting screen for setting up the brightness of the screen.

By the way, if you get an LCD from Sparkfun make sure you select the correct voltage. I bought mine 5V but my two FTDIs are 3.3V. I had to convert one to 5V to avoid using an external source.
