Not sure if this applies to micro:bit, but with many circuit boards you can use `tone(pin, frequency, duration)` to play a certain frequency on a pin. It’s possible that [Code.org](http://Code.org) doesn’t support playing sounds on micro:bit, so you may need a different program.

However, it can only [produce audio output](https://microbit.org/get-started/features/sound-output/) when connected to headphones, or if you have a newer model with a built-in speaker.
