Final answer:
Fritzing is open source and free software used for designing electronic circuits, prototyping, and creating PCBs.
Step-by-step explanation:
Fritzing is indeed open source and free software. It is a popular tool used for designing electronic circuits, prototyping, and creating printed circuit boards (PCBs). Fritzing provides a user-friendly interface with a drag-and-drop feature that allows users to easily design circuits.
It includes a vast library of electronic components that can be added to the design, such as resistors, capacitors, microcontrollers, and sensors. In addition to designing circuits, Fritzing also offers features for creating schematics and PCB layouts.
Users can easily switch between different views to see their design from different perspectives. As open-source software, Fritzing is available for free under the GNU General Public License, allowing anyone to use, modify, and distribute the software.
