Rule against Sirens?
Good evening, CD!

I just picked up a RadioShack 273-079 12VDC Piezo Siren from (guess where) RadioShack, in hopes to integrate it into our DS. After hooking it up to a supply, I have come to realize that this siren is VERY loud. This is ideal for a competition setting, as it will certainly get the driver's attention. My question is, are there any rules against creating noise from your DS (or robot for that matter)? I did a quick skim over the rules again, and couldn't find anything, but wanted to make sure.

Also, is there anyway to control volume for a piezo buzzer? Something tells me no (I've tried varying voltage with no avail), but I figured I'd ask.

Thanks!
Jacob

EDIT: after reading, it looks like maybe I can use PWM to control the volume.
