check make sure your piezo has a biult in driver circiut if not it wont sound so test it off a 9 volts batteryI see three battery connectors. Where are the 9-volt batteries that connect to them?
I don't have them plug in because when I did nothing happened. The piezo tranducer make no sound and the LED never turned on. Btw, I got the wrong led so,i'm gonna get another one tomorrow.
