# Set Pull
|
|
|
|
Configure the electrical pull of the specified pin.
|
|
|
|
Many @boardname@ pins can be configured as _pull-ups_. For example, a
|
|
pull-up can set a pin's voltage to high (3.3 volts, or `1` when
|
|
calling [digital read pin](/reference/pins/digital-read-pin)). If one
|
|
end of a button is connected to ``P0`` (set to high) and the other end
|
|
is connected to ``GND`` (0 volts), then when you press the button,
|
|
``P0`` is driven to 0 volts, and the @boardname@ software can detect a
|
|
button press.
|
|
|
|
```sig
|
|
pins.setPull(DigitalPin.C9, PinPullMode.PullDown);
|
|
```
|
|
|
|
The pull-up and -down resistors are about 13kOhm.
|
|
|
|
## Parameters
|
|
|
|
* ``name``: The @boardname@ hardware pin to configure (``P0``-``P20``)
|
|
* ``pull``: The pull to which to set the pin (**down**, **up**, or **none**)
|
|
|
|
## Example
|
|
|
|
The following example sets the pull of pin ``P0`` to **up** (high).
|
|
|
|
```blocks
|
|
pins.setPull(DigitalPin.P0, PinPullMode.PullUp);
|
|
```
