\section{Requirements}
\begin{itemize}
\item large pcb board
\item fused power input - EDIT: instead I will have a case around the nano, 3d printed, and have the case connect into the pcb, i.e. cutouts for the case in the pcb, and clips on case. the rest of the pcb will be fused somewhere, after the nano. but nano powers it.
\item arduino nano
\item switch to activate things
\item rotary to change number
\item 7 digit display to list number, and shift register, resistors
\item  explanation of what numbers do on board
\item 3d printed cover over nano
  
  
  
  \end{itemize}

\section{build notes}
The 7 segment symbols are abstracted in kicad. Job security for engineers.

The example gave a common Vcc, with all pins being connected to GND, and sinked when on.

The data sheet of the 7seg, omits the schematic. but does show that it is common anode, or common vcc. Pin 3 is left out, but that is VCC.
