I wish that I could build this very simple project however, you left no schematics to build.

Hi Backpacker, Sorry for the delay, I have been away from my computer for a while. The wiring is quite simple you take the +VE from the dc piezo buzzer (these are the ones with an in built driver circuit) to Arduino PWM pin 11 and connect the ground of the buzzer to the ground pin of the Arduino. So just 2 wires to connect.
