# Servo Write Pin
|
|
|
|
Write a value to the servo on the specified [pin](/device/pins)
|
|
and control the shaft.
|
|
|
|
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.)
|
|
|
|
```sig
|
|
pins.servoWritePin(AnalogPin.P1, 180)
|
|
```
|
|
|
|
### Parameters
|
|
|
|
* ``name``: a [string](/reference/types/string) that specifies the pin name (`P0` through `P4`, or `P10`)
|
|
* ``value``: a [number](/reference/types/number) from `0` through `180`
|
|
|
|
### Examples
|
|
|
|
#### Setting the shaft angle to midpoint on a servo
|
|
|
|
```blocks
|
|
pins.servoWritePin(AnalogPin.P1, 90)
|
|
```
|
|
|
|
#### Controlling the shaft by using the tilt information of the accelerometer
|
|
|
|
```blocks
|
|
basic.forever(() => {
|
|
let millig = input.acceleration(Dimension.X)
|
|
// map accelerometer readings to angle
|
|
let angle = pins.map(millig, -1023, 1023, 0, 180)
|
|
pins.servoWritePin(AnalogPin.P1, angle)
|
|
})
|
|
```
|
|
|
|
#### Setting the full speed on a continuous servo
|
|
|
|
```blocks
|
|
pins.servoWritePin(AnalogPin.P1, 0)
|
|
```
