When mounting Arduino-based projects in locations that don't lend themselves to easy access - such as an attic or shed some distance away, it can be a trial to upload new sketch revisions or experiment without some effort. However it's easy to upload sketches remotely with a wireless link to the Arduino instead of a USB cable with an XBee.
As these tiny modules can operate as a serial bridge, by mounting one in the remote project and another at the local PC you can then upload sketches or monitor serial data output with ease. This process has been documented by Jordan Tallent who shows how easy it is.
Although he's used 3.3V Arduino-compatible boards, it's easy to use XBee shields or a level converter to work with 5V (e.g. Uno-compatibles) without any effort.

If you're interested in Arduino but not sure how to learn - order one of our Experimenter's Kit for Arduino:
The package includes a wide variety of parts, sensors and modules including: a servo motor, lights, buttons, switches, sound, sensors, breadboard, wires and more. Furthermore a Freetronics Eleven Arduino-compatible board is included to make this an extensive hobby experimenter, inventor and starter kit.
