There are two kinds of piezo buzzers: active and passive. The active one that plays a specific pitch when powevered and is not good for this purpose. The passive kind functions like a speaker, reproducing the pitch you apply to it. You can test the piezo speaker with the "blink" ...
Connect the positive side of the buzzer to digital pin 3, then the negative side to a1k ohm resistor. Connect the other side of the 1 k ohm resistor toground(GND) pinon the Arduino. Remember to connect the buzzer the right way, the buzzer has positive and negative pins! So basically ...
