I like the Arduino. The UNO in particular.
However, along with many others, I have difficulty easily seeing the pin names/numbers.
Don’t get me started on reading values of transistors and ICs, as there is not much that I can do about that, other than get a handy magnifying glass.
But, I can do something about the Arduino UNO, so I have created an Arduino Paper Shield.
Step 1: Not So Much an Instructable, More of a Helping Hand.
Created in the freely available fritzing, found at http://fritzing.org/home/
To those who are not aware of fritzing, it is a free or contributable piece of software that allows you to construct drawings and diagrams, even PCB data, for your projects with a large range of common components.
It is not specific to Arduino and is definitely worth investigating if you have an interest in electronics.
For the Paper Shield, I have added the fritzing file and a pdf file for the shield to download, added here in zip file but also stored at
Select ‘The Arduino Paper Shield’ box to open up the explanation and access the pdf file and or the fritzing file.
The fritzing file name will need to be changed from .txt to .fzz to open in the fritzing application.
This is due to some strange 'security stuff' on the website.
There are also a couple of photographs on the site showing the shield attached to an Arduino UNO.
Best results are when printed on reasonably thick card. Make sure you print out at 100% to retain scale.
There are five different orientations for you to choose from and hopefully at least one will help you as much as they have helped me.
The three black dots line up with three of the four standoff holes in the Arduino.
- Drill out the standoff holes and all of the pin holes on the shield.
- The shield can then be fixed to the Arduino using standoff posts.
- You can either insert female headers into the Arduino (holds the shield in place) or just access the pins as you normally would.
