A lot of people like fancy GUIs and nice graphics, but some of us just feel more at home in a command prompt. [nevdull] is one of those people. Instead of just using the Arduino dev tools that are available for download, he wanted the ability to shell into his Arduino, so he created AVR Shell. AVR Shell is a UNIX-like shell that allows you to “log in” to your Arduino/AVR and see what’s really going on; letting you read registers, scale the CPU speed, create/edit/delete variables, and even set up timers. The shell is even user-customizable! Those of you interested in Arduino shells might also check out bitlash, another open source CLI. Someone ought to hook this up to the Internet enabled Furby and get Flite compiled on there, letting us shell into a Furby from miles away to make it talk.
