Arduino enthusiast Rohit Gupta has written a useful Windows-based program to interface with an Arduino board. It would be useful for testing hardware connected to digital output pins and also reading the values returned from analogue inputs - great for testing prototype hardware without having to insert temporary testing code in sketches. However you do need to upload Rohit's sketch to interpret the commands from the PC. Watch the following snazzy video for a demonstration:
