Documenting your IoT projects using Fritzing

I have build several IoT projects for my Gadgeteer and Raspberry Pi projects.

Although , as a software developer, figuring out how everything works with these intriguing components is challenging, the real challenge is documenting.

And with documenting I mean the choice of components, the layout and wiring, the use of GPIO ports, the code, pictures, etc.

Yes, it’s nice to see your projects succeed but it’s even better if you can tear everything down and rebuild it again. And to see it’s still working 🙂

I was looking at Hackster for some information and there they were shown: nice layout schema’s with in the right bottom corner the word ‘Fritzing’.

So I went do the site:

“Fritzing is an open-source hardware initiative that makes electronics accessible as a creative material for anyone. We offer 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.”

Then I downloaded the Win32 tool and it is pretty easy to use:


What I use is the breadboard function. Just pick the component you have used from the parts list and place them on the breadboard of your choice. Each component has several options, properties. And you can flip and rotate them. And you can simply drag lines which will become wires.

Tip: change the color of the wires. Use red and black for 5V and ground. Your readers like that a lot.


Here I added a Raspberry Pi, a breadboard, a led and a resistor. Se that I can add a header and some comments too.

It’s easy to export this as a picture:


But if you are really proud of this project you can share it on the Fritzing site:


Do not forget to add a picture or video to make the project more attractive (Use a better camera, please):


This proofs your project is really working. That way you take a lot of doubt away from your readers.

So please give it a try. Share your projects here in the comments.
