|
||
|
|
|
||
|
|
Specify which [pin](/microbit/device/pins) (P0, P1, P2) is used to generate tones.
|
||
|
|
|
||
|
|
```sig
|
||
|
|
pins.analogSetPitchPin(AnalogPin.P0)
|
||
|
|
```
|
||
|
|
|
||
|
|
### Parameters
|
||
|
|
|
||
|
|
* `name` - [String](/microbit/reference/types/string); the pin name ("P0", "P1", or "P2")
|
||
|
|
|
||
|
|
### Example
|
||
|
|
|
||
|
|
```
|
||
|
|
pins.analogSetPitchPin(AnalogPin.P0)
|
||
|
|
let frequency = 440
|
||
|
|
let duration = 1000
|
||
|
|
pins.analogPitch(frequency, duration)
|
||
|
|
```
|
