The piezospeaker and servo circuits will remain connected to your board for the rest
of the activities in this text.
All circuit schematics from this point onward will show circuits that should be added

All wiring diagrams will show the circuit from the schematic that comes just before it
along with the servo and piezospeaker circuit connections.
