While looking at prototyping tools for my Fez Domino, I came across Fritzing, a software that allows you to easily diagram your electrical circuit! Here is a summary:
- Open source, so free
- A community of enthusiasts
- Dozens and dozens of components, and the community continues to increase the available quantity
- A shop for manufacturing your PCBs. (Coming soon)
- Multiplatform
- Multilingual
- A really great visual, both of the software and the circuits!
Here are my three views that I tested of the same circuit:
Breadboard
Schematic
PCB
Happy prototyping!
