Hi Blakbird,
Little note about 4.5V motor: when you say “The motor is DC, so polarity is
not important.”... precisely since it is a DC motor, polarity IS important,
rotation direction depends on it...

Good point, Philo. I did not choose very good wording here. What I meant was
that, as a DC motor, there is no “hot” terminal and no “neutral” terminal.
Therefore, you cannot hook it up wrong and damage it. I’ll go back and see if I
can clean up the wording a bit.
