Arduino LCD Keypad
I have an Arduino LCD Keypad Shield V1.1 connected to an Arduino Duemilanove. I am trying to produce a square wave audio frequency of 1-20 hertz. I want the LCD to display the current output in Hz and be able to control the output frequency using the push buttons. Any ideas?

Are you trying to control the Arduino from LCD Smartie? (like on this page http://www.nuelectronics.com/estore/?p=9 )
Smartie is only meant to display text and PC system information on supported LCD modules, not act as a general purpose interface between the PC and microcontroller boards. It appears that somebody has implemented a Matrix Orbital LCD "emulator" on the Arduino platform, but Smartie can't easily control any "extra" non-standard features on this.
If you want to produce square wave outputs on the Arduino, you need to modify its firmware, and that's entirely separate from Smartie. This forum is really about the Smartie software itself, with some support for LCD hardware related to Smartie. If you need info on the Arduino itself, you need to look at Arduino forums/documentation.
