    I am looking for a component to control from a microcontroller to make
    a beeping noise, nothing to loud but to sound electronic and not like a
    buzzer. I just need an audible alert that is not to irritating. Any ideas
    would be great, I don't have a DAC on the microcontroller, and the
    simpler the better.

    Go to a Radio Shack store if there are any in your area, they have beepers.

  3. Or the traditional way, a unijunction transistor feeding a speaker,
    which beats a 2transistor multivibrator feeding a speaker since it uses
    one active component (albeit one likely harder to find).

    555s basically took over that field when they came along.
