doesn't seem to work. Nor does this: http://code.google.com/p/arduino-tiny/
Are they just outdated, and if so can I just revert back to an older version of arduino IDE?

I'm using the latter with v1.0.3, what is the specific problem? ... "doesn't seem to work" is a bit broad.

[Reply #2 on:]

The entire ATTiny works fine. I can blink an LED. But when I use tone() with a speaker, nothing happens. I'll try it with 1.0.3 now and see if that makes a difference. (I've been using 1.0.1 up until now)

So I re-installed arduino as 1.0.3. Also re-installed the core you used. Built the circuit correctly. Made sure that a normal LED sketch works. (It does.) The tone() still won't work.

The tone() still won't work.

Wanna bet?

[Reply #5 on:]

Post your code, I'll have a look and/or give it a try.

[Reply #6 on:]

I doubt it's actually the code, seeing as how it's just a simple test:

Code:

void setup() {
}
void loop() {
  tone(3, 2000, 500);
  delay(500);
  tone(3, 3500, 500);
  delay(500);
}

I'm thinking something is different about the core, but I followed the readme.txt exactly... :/

Works fine here.

Pin 3 is on the left side of the processor one down from the top.  What's connected to it?

[Reply #9 on:]

The speaker (which I know works) connected to ground.

[Reply #10 on:]

...with a speaker...

An 8 ohm speaker?

[Reply #11 on:]

No, it's a buzzer. I think it's called a piezzo buzzer. And I know it works with the tone() function on the arduino.

[Reply #12 on:]

Hmm. And an LED will blink on the same pin?

[Reply #13 on:]

Yes.

[Reply #14 on:]

Load the blink sketch, blink an LED on pin 3, say 100ms on and 100ms off. Once that is working, add the piezo to the circuit, from pin 3 to ground (through a small resistor, 100 ohms or so is best if you have one.)

What do you hear from the piezo?
