Questions & Answers

If the buzzer is connected to a AAA battery, will it get damaged?

There are five volts in them. There are one hundred and one AAA batteries in a single pack.

By how many decibels (dB) is that loud? It will be loud enough for what I want to do, but I am trying to find out. ?

85 dB is the sound level of the alarm buzzer.

When is the tone to be played? How can I vary the frequency? Are you able to use this with only a straight DC ?

As far as I know, there is no way to adjust the tone for these quadcopters. You can basically adjust the duration of the tone, but not the pitch of it - I've found that you can only adjust the on/off.

I'm very pleased with it

4/5

There is a lot of noise. One possible dislike is the volume might be a little too high at times.

This buzzer can be used on motherboards and is perfectly functional

5/5

The volume of a computer buzzer is normal. Hand soldering some wires and crimping dupont 2 were my contributions to the project.
