Fritzing review

Fritzing is an open-source initiative to support designers, artists, researchers and hobbyists to work creatively with interactive electronics. We are creating a software and website in the spirit of Processing and Arduino, developing a tool that allows users to document their prototypes, sharethem with others, teach electronics in a classroom, and to create a pcb layout for professional manufacturing.

In a nutshell, this software acts like a virtual breadboard for tinkering with electronic kits. You can even program an Arduino from within Fritzing without leaving the app, and you can add your own parts (Sparkfun’s comes with the software natively, see also Adafruit’s part repository).
