Buzzer component

I am using the stock component. To play more than 1 tone, it seems that one has to add the component for each tone.
It would be nice if one could specify the pitch and duration when calling it.

Hello.
That is not how the Buzzer component is intended to work.
The Buzzer component is a single fixed frequency component only sets an output to high or low, depending the buzzer is on or off.
With actual hardware to make it buzz, a fixed DC supply e.g. 9v is used to enable buzzer.
For a buzzer of different frequencies, then a loud speaker, amplifier and PWM will be required.
If less harsh tone, then you could use a DS sine generator.

Hello,
The Buzzer component is targetting fixed frequency buzzers, while the simulation outputs a tone the hardware will simply turn an output on and off. Martin beat me to it
I beleive what you're after is the Piezo component which targets a variable frequency device which is much more like a solid state speaker. This requires a audio frequency output to it and has a function "BuzzerOnDelay" which has the two parameters you specified.
Hope this helps.
