Fritzing is an open-source initiative that allows you to virtually design electronic circuits on a breadboard (although you could design circuits that aren't on a breadboard). This could save a lot of hours working on a breadboard if you have this amazing software at hand.
Fritzing can be seen as an Electronic Design Automation (EDA) tool. The input metaphor is inspired by the environment of designers (the breadboard-based prototype), so that it is easy to transfer a hardware sketch to the software by using a drag-and-drop-based GUI to copy your sketch.
In this new version of Fritzing a high-level summary of changes are:
- Upgraded to Qt5, version 5.2.1;
- Fix for AtMega-IC;
- Fix for -svg command line option, updated -help output;
- Adding a lots of new parts, e.g. Atlas Scientific sensors, Teensy 3.0/3.1 and so on;
- Remove old comment;
- Fix for pcb -> schematics ratsnest missing issue.
