Assembling this project involves connecting a piezo buzzer's leads to Raspberry Pi GPIO pins.

Connecting a piezo buzzer to the Raspberry Pi is a blast, but don't be alarmed.  It is also easy to do.

 Here is a wiring diagram for this project:

Connect one of piezo leads to ground on the Raspberry Pi.  The other piezo lead goes to GPIO pin 22.  It is the 8th pin down, in the left column, from the end closest to the SD card slot.
