# Analog Read Pin
Read the specified [pin](/microbit/device/pins) (P0, P1, P2) as analog.
```sig
pins.analogReadPin(AnalogPin.P0)
```
### Parameters
* name - the pin name (`P0`, `P1`, or `P2`)
### Returns
* [Number](/microbit/reference/types/number) - a number between 0 and 1023 (included)
The following code reads `P1` and charts it on the screen:
```blocks
basic.forever(() => {
let value = pins.analogReadPin(AnalogPin.P1)
led.plotBarGraph(value, 1023)
});
```
