# Analog Write Pin
Write an **analog** signal (`0` through `1023`) to the
[pin](/device/pins) you say.
```sig
pins.analogWritePin(AnalogPin.P0, 400)
```
## Parameters
* ``name`` is a [string](/types/string) that is the pin name you say (`P0` through `P4`, or `P10`)
* ``value`` is a [number](/types/number) from `0` through `1023`
## Example
This program writes `1023` to pin `P0`.
```blocks
pins.analogWritePin(AnalogPin.P0, 1023)
```
### ~hint
When you tell it to write `256` (for example), this function does not
_really_ write `256`. Instead, it writes a lot of different numbers,
and their average is `256`.
