[dorkbotpdx-blabber] Arduino posibilities

[Alex Norman]

for beeping you can use a piezo transducer [called a 'buzzer' at radio shack].

I assume the arduino gives you the pwm outputs, hook the transducer to that,
maybe with some filtering, and you can make sound.

looks like there is a little tutorial about it already:
