Using the test rig that we recently built in the 'side project'
to characterize diodes and demonstrate the Shockley diode equation
that relates forward current to forward voltage.
This is the first step to characterizing transistors. Next
episode will use the same test setup to measure a transistor
and demonstrate how it's a voltage-controlled current source.

Files documenting the test rig can be found on the project GitHub:
