arduLCDkeypad - Atmega328 LCD piggyback board (I2C and Serial)

Hi

I've wanted to make a smarter LCD piggyback board that would also handle the 5x4 keypads for some years and I finally got around to it.

This board is a minimal design, Atmega328 using internal 8Mhz oscillator, features include DC piezio, variable control of contrast and Backlight. Connect via I2C or Serial.

There some changes I would make to version 2 of this board but it woeks pretty well as it is.

You'll find all the eagle files, Gerber files, Schematic PDF, arduLCDkeypad source code, library code at Github. Please use it at will, modify it, improve it.

The code isn't optimized, not as clever as some that i've seen around but its going and I do have other project to get into.

Thanks
