# Servo Write Pin
Writes a value to the servo on to the specified [pin](/device/pins) (``P0``, ``P1``, ``P2``), controlling the shaft accordingly.
Write a value to the servo on the specified [pin](/device/pins)
and control the shaft.
* on a standard servo, this will set the angle of the shaft (in degrees), moving the shaft to that orientation.
* on a continuous rotation servo, this will set the speed of the servo (with 0 being full-speed in one direction, 180 being full speed in the other, and a value near 90 being no movement).
This function will move the shaft of a standard servo to the specified
angle, or set the speed of a continuous rotation servo. (`0` specifies
full speed in one direction, `180` specifies full speed in the other,
and approximately `90` specifies no movement.)

### Parameters
* `name` - [String](/reference/types/string); the pin name ("P0", "P1", or "P2")
* `value` - a [Number](/reference/types/number) between 0 and 180 included
* a [string](/reference/types/string) that specifies the pin name (`P0` through `P4`, or `P10`)
* a [number](/reference/types/number) from `0` through `180`
