Garage Door Controller This project controls and monitors a Garage Door using XBee and Google Talk. It is described here

Chatduino This is a client for the AOL chat service, which allows you to communicate with your Arduino projects from anywhere on the interwebs. It is described in detail here

Droplet (AKA ChumBee, and formerly as XBeeArduinoService) A wireless (XBee) display/remote control for quick information (twitter, calendar, news, weather etc.). Droplet is designed for easy customization with pluggable services. This project is detailed here

XBeeMotion A PIR motion detector, made wireless with XBee radios. Motion events are sent over Google Talk. It is discussed here

LCD4x20ArduinoLibrary is an Arduino library for interfacing with an HD44780 LCD. The library was written for Droplet but may be useful for a variety of projects. This library differs from others in that in properly shifts content up as the display becomes full, and understands the line feed character (10). For example, "the\nquick\nbrown\nfox" will display on four lines. This library is designed for 4-bit mode, requiring only six I/O pins for communication (4 data bus, RS and Enable).

LedColorPicker is a Java color picker that controls an RGB LED via an Arduino. This project is detailed here.
