As explained in my comments in issue #3, after doing some research into generating random values with Arduino, I believe the following changes will produce results with better randomness than before:
Generates a much more random value as an input to randomSeed() by taking multiple measurements of the floating analog pin
Only calls randomSeed() once, as it should be enough for the duration of a single test, or even multiple tests in a single day
Adds a sentence to the README to be clear that A0 needs to be floating for randomness to work
