Code structure
The split flap is made up of a 2D array of split flaps called Bits. The BitArray class controls all of the bits from
one place. This is where you would print anything to the screen, or do any animations.
Create a new BitArray object, and call the functions inside to change what is displayed on the screen.
display_layered_strings() is the highest level function for printing to the screen, printing an array of strings in any formatting you would like (see the docstring for more info)
Many different functions have been created to make writing to the screen as easy as possible.

Questions
What parts does the Bertha3 use?
8 parts, built around the 74HC595. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Bertha3 KiCad files?
From the jarviscog/Bertha3 repository on GitHub, at the commit this page was made from: the board is PCB/PCB.kicad_pcb and its schematic PCB/PCB.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Bertha3 design in my own project?
Its repository states no licence, so its author keeps all rights: ask jarviscog before reusing the design.
