fritzing: fritzing (electronic prototyping) fritzing: fritzing: Fritzing is an open-source initiative to support designers, artists, fritzing: researchers and hobbyists to take the step from physical prototyping fritzing: to actual product. It allows users to document their Arduino and other fritzing: electronic-based prototypes, and to create a PCB layout for fritzing: manufacturing. fritzing: fritzing: fritzing: fritzing: Homepage: http://fritzing.org/
