Uhclem has posted a wireless Arduino message board project on Instructables. The heart of the project is the Arduino with the Atmega328 interfaced with a Sparkfun Series I Xbee module, serial EEPROM and LDR. The display is an a LCD-compatible Noritake CU2009ECPB-W1J VFD character display compatible with the LiquidCrystal library.
The purpose of this project was as a substitute for a list of chores contained on sticky notes. Messages are relayed to the board from a Linux or PC terminal program via a USB Xbee carrier. Schematic and Arduino code are provided. (The sketch takes up much of the Arduino’s onboard flash, and there is a provision for message storage on the optional EEPROM.)
