U must use a half power transistor... and its so simple!!
if U had more questions about eletronics... just ask me!!

yeap buddy!!
u can use a half power transistor like tip41 or some thing like this!!!
download the datasheet..
connect base (PIN1) to microcontroller
connect collector (PIN2) to GND of Piezo buzzer...
connect emitter (PIN3) to GND of Ur circuit...
and at the end controll in with Ur microcontroller!!!;)
