Fritzing online circuit simulator: No need for Hardware to design a circuit
In the world of electronics and IoT, prototyping circuits before real-world implementation is crucial. But what if we told you that you don’t need any hardware to design and simulate circuits? Enter Fritzing – a free online circuit design tool and Arduino simulator.
Fritzing software tool is a free online circuit simulator, an ultimate tool that you can use to create an electronic circuit and component diagrams for use with rapid-prototyping development boards such as the open-source Arduino called Arduino Simulator online.
Fritzing allows anyone, from hobbyists to educators, to create virtual circuits, visualize wiring diagrams, simulate electronic behavior, and even generate production-ready PCBs.
Whether you’re building your first Arduino project or teaching electronics to students, Fritzing helps you bring ideas to life – without soldering a single wire!
What is Fritzing Software Tool?
Fritzing is an open-source software developed to support designing, documenting, sharing, and manufacturing electronics using an intuitive visual interface.
It is entirely cross-platform and well supported – you can guarantee that it can be used on any Arduino project to show you how to make connections and wire things together using it.
It offers a software tool, a community website, and services in the spirit of Processing and Arduino, fostering a creative ecosystem that allows users to document their prototypes, share them with others, teach electronics in a classroom, and layout and manufacture professional PCBs.
Core Features:

Download and Start:
Select the download for your platform below.
Installation Instructions:
Installing the Fritzing software tool
Please make sure your system satisfies one of these requirements:
Windows – XP and up
Mac – OSX 10.7 and up, though 10.6 might work too
Linux – a fairly recent linux distro with libc >= 2.6
- Start downloading the Fritzing package that’s right for you.
- Unzip your Fritzing folder somewhere convenient on your hard drive.
- This may also be a good time for you to create a shortcut to the Fritzing application.
- A free unzipping program can be found here, should you need it.
- If you are updating your release of Fritzing, your custom files (parts and bins) are not stored with the application, so they will not be destroyed if you delete the older version of the Fritzing application folder.
- To start Fritzing:
- onWindows: double-click fritzing.exe
- onMac: double-click the Fritzing application
- onLinux: double-click Fritzing, or try ./Fritzing in your shell window
- If you experience problems, please try downloading it again. This often helps. If it doesn’t, have a look at our forums.
Mac notes:
Recent versions of OS X do not allow “unverified” software to be launched directly. In order to run Fritzing, you will need to either:
- right-click the Fritzing icon and select “Open”
- in the warning dialogue, click “Open”
or, to get rid of the warning permanently:
- go to the System Preferences
- open the Security & Privacy page
- unlock it by clicking the lock in the lower-left corner
- set it to allow app downloads from anywhere
Linux notes:
This binary release has been built and tested under Ubuntu 12.04 LTS.
Distros for other flavors of Linux can be found at openSUSE’s repository, at Heinervdm’s openSUSE repo; including a one-click download for openSUSE. Search our forum for even more. Fedora users can install Fritzing with ‘yum install fritzing’.
We heartily thank openSUSE, Thomas Zimmermann, Debian.org, Bruno Canning, the Fedora Project, Ed Marshall, and other people and organizations for making these available. (But please be aware we have not tested these builds.)
Learning Fritzing: Tutorials for Beginners
Fritzing offers a self-paced learning ecosystem:
Popular Beginner Tutorials:
| View | Topic |
|---|---|
| Breadboard View | Building a circuit visually |
| Schematic View | Understanding wiring diagrams |
| PCB View | Creating double-sided boards |
| Custom PCB Shapes | Add creativity to your board |
| Stripboard View | For prototyping without PCBs |

Fritzing Software Interface:
Fritzing has three main interface views:
Breadboard View – Drag & drop components on a virtual prototyping board.
Schematic View – Logical representation of the circuit.
PCB View – Place components and tracks for actual fabrication.
Each view auto-updates based on changes in others. That’s seamless multi-layer integration!
