Buzzer? Piezo?

You guys are awesome you really are, I mean you guys get bombarded with questions often the same questions over and over.

I watched a video that was presented to me by Engadget blog.
There was a video [The video] with a MicroMouse maybe some of you are familiar with them. But anyway, I was curious as to what the person in the video is using to make the "beep" that signals the initial start of the micromouse.

I bought a few Piezo buzzers from adafruit just to play with when I seen this video.

But with the 0-255 range I can't seem to get the tones generated in the video.

Are you using the Tone Library...

Oooooh.. Shoot. Didn't know there was a tone library. Thank you very much! :slight_smile:
