user13371: I bought a 10 V Piezzo electric buzzer and I wonder how to connect it to an Arduino (in my case a Lilypad USB, but the question stands for any Arduino I guess...).
I hadn't realized this was a 10V buzzer, whereas the Arduino will support at most 5V. 
I tried a simple layout such as below, with the sample code from a sparksfun tutoral, but that's not working!
 
So, how can I do it? ... or should I use another buzzer ?
Thanks

user7856: Your options:

Try it anyway with 5V: the buzzer might still produce loud enough sounds for your needs.
Use the line from the arduino to drive an "amplifying" stage (ex: 2N2222 in ON/OFF mode) - but this will also require a 10V source (like a step-up voltage converter)
Get a piezo that is designed to operate at 5V
