Track
Alternating between 2 loops of track.
When a sensor is triggered track power will switch to the
other loop of track.
Note differences in terminals 3,4, 5, and 6 between
AC trains and DC trains.
AC trains generate electrical noise which affect the microcontroller,
so an external power source must be used.
Trains must carry magnets to trigger sensors
AC or DC trains
DC trains only
