* a [string](/reference/types/string) that stores the name of the pin * a [string](/reference/types/string) with the name of the pin

#### ~hint
If you are using **analog read pin** with another micro:bit
running **analog write pin**, it is a good idea to check
**analog read pin** many times and then take an average.

# Analog Write Pin # Analog Write Pin
Write to the specified [pin](/device/pins) (P0, P1, P2) as analog. Write an **analog** signal (`0` through `1023`) to the
[pin](/device/pins) you say.

### Parameters ### Parameters
* `name` - [String](/reference/types/string); the pin name ("P0", "P1", or "P2") * a [string](/reference/types/string) that is the pin name you say (`P0` through `P4`, or `P10`)
* `value` - a [Number](/reference/types/number) between 0 and 1023 included * a [number](/reference/types/number) from `0` through `1023`
The following code writes `1023` to the `P0` pin: ### Example
This program writes `1023` to pin `P0`.
```blocks ```blocks
pins.analogWritePin(AnalogPin.P0, 1023) 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`.
