Post subject:  Piezo speaker on Uno

Hi. I've tried connecting a piezo speaker using the motor/servo setups and with the speaker selection but nothing works. Has anyone successfully connected a piezo and gotten it to work make any sound other than a 5V hiss?

If so, could you tell me what motor type you used and which pin(s)?

Thanks in advance for your help.
