Some test scripts will need to be run across this test procedure. These
test scripts can be found in the \textit{software/} folder of the CONV-TTL-BLO
\textit{git} repository~\cite{ctb-repo}. One way to obtain this repository is
by running the following command in a Linux command line:
\begin{small}

\verb+git clone --depth=1 git://ohwr.org/level-conversion/conv-ttl-blo.git+
