# Analog Pitch
|
||
|
|
|
||
|
|
Emits a Pulse With Modulation (PWM) signal to the current pitch [pin](/microbit/device/pins). Use [analog set pitch pin](/microbit/reference/pins/analog-set-pitch-pin) to set the pitch pin.
|
||
|
|
|
||
|
|
```sig
|
||
|
|
pins.analogPitch(440, 300)
|
||
|
|
```
|
||
|
|
|
||
|
|
### Parameters
|
||
|
|
|
||
|
|
* `frequency` : [Number](/microbit/reference/types/number)
|
||
|
|
* `ms`: [Number](/microbit/reference/types/number)
|
||
|
|
|
||
|
|
### Example
|
||
|
|
|
||
|
|
```
|
||
|
|
pins.analogSetPitchPin("P0")
|
||
|
|
let frequency1 = 440
|
||
|
|
let duration = 1000
|
||
|
|
pins.analogPitch(frequency1, duration)
|
||
|
|
```
|
||
|
|
|
||
|
|
### Some common notes
|
||
|
|
|
||
|
|
* 440 = A4 on piano
|
||
|
|
* see [piano key frequencies ](https://en.wikipedia.org/wiki/Piano_key_frequencies) for more information
