this simply blinks the LEDs in the 10 segment display
in order at a frequency that depends on the measured output of the
It might look cooler without all the wires hanging out,
but those are the only wires I have, and I have four breadboards, but
they are all minis (like this one).

I have read that this should not be done this way:
each LED should have it's own resistor between its cathode
As I understand it, this is done to protect any LED that may provide less resistence
than the other LEDs.
Such an LED would get a higher voltage flowing over it,
possibly burning it out, shortening its life, or leaving the
other LEDs underpowered and dim.
That way you could have more than one LED on at a time
(which this program does not do).
