The circuit diagrams in these notes were created using an application called Fritzing. You will need to create similar diagrams to document your work.
Fritzing comes with a library of graphics which represent different types of component. The library includes many Arduino boards, but some parts, such as the Particle Argon microprocessor are not included as standard.
This page explains how to import the custom parts that you need to create diagrams based on the Particle Argon.
Step 1: Install Fritzing
Follow the installation instructions on the Fritzing Web site
Step 2: Import parts
Search the web for any parts that you need. They will have a
Download the parts into a known directory on your laptop.
Make sure that the extension of the downloaded file is .fzpz and not .zip
Open the Fritzing app
In the parts navigator on the right-hand side, click the menu icon and choose
Navigate to the directory where you saved the Argon part and click Open/Upload
Step 3: Create diagrams
The Fritzing interface is very intuitive but if you need some help getting around, there are Web and video tutorials available on the Fritzing Web site
A good diagram is one that is easy to understand when it is seen for the first time. Here are a few rules of thumb that you should apply to your layouts:
- Make sure that your components are correctly connected to the breadboard where possible
- Colour-code your wires using red for power, black for ground and other colours for any other type of connection.
- Avoid crossing wires - move your components around on the breadboard to create the required space.
- Avoid wires at arbitrary angles. You can add corners to your wires just by clicking, and you can snap them to the layour grid by holding dow the SHIFT key as you move the points.
