That is true.  One must have very good eyes to see a one microsecond pulse
that only happens one per second.  Blink and you miss it.

The LED might work but the "for sure" way is to send the PPS to a flip flop
so you can see the state change at 1Hz.  Use a solderless bread board and
5V power supply.
