your talking about a transistor as a voltage follower?
i didn't want to do that because, i want to keep it as simple as possible. thats the reason i didn't want to build a small amp
and about using 2 pins, if i run exacly the same program on 2 pins and conect them to the same speaker i'll get a louder sound? i'll try that:D
by the way, i want to conect 5 speaker, each making a "click" sound at random times
thanks!
