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

### Parameters
* name - the pin name (`P0`, `P1`, or `P2`)
* a [string](/reference/types/string) that stores the pin you say (`P0` through `P4`, or `P10`)
### Returns
* [Number](/reference/types/number) - a number between 0 and 1023 (included)
* a [number](/reference/types/number) from `0` through `1024`
The following code reads `P1` and charts it on the screen:
This program reads pin `P1` and shows the number as a
[bar graph](/reference/led/plot-bar-graph).
