Hey all. So I'm a total beginner to everything having to do with electronics. To the point where i'm still not quite sure exactly what resistors do. Regardless, i've been having loads of fun going to the dump and picking up old computers and such, taking them apart (I learned the hard way the hazards.) and messing with the little pieces that I know how to work with. So far, all i've really been making are super simple circuits, with two AA batteries, a bunch of switches, and a few LED's.
While taking apart the computer, I found and removed a small speaker. I became curious about how to make it project sound, so I hooked it up with 3 volts, and heard a little popping sound whenever I switched it on or off. This amused me for about five minutes, but I really wanted it to do more than just pop. How would you use the speaker to make any kind of noise? For instance, if I wanted to make a buzzing kind of sound, how would that work? Is there a special kind of speaker that buzzes when you run power through it? Let me know. Any advice from people who know what they're doing would be greatly appreciated. Thanks.
