# Brake/throttle

#### brake()

{% tabs %}
{% tab title="Description" %}
Set up a device that output variable voltages, typically a load cell, hall sensor or potentiometer, to controll the brake joystick axis. Should be wired [like this](/ddc/2.-wiring/analog/analog-wiring.md). It is considered an analog switch, and will have to be assigned a[ switch number](/ddc/1.-project-planning/analog-inputs.md) and you'll have to[ read out](/ddc/1.-project-planning/analog-inputs.md#reading-a-value) some values to [calibrate](/ddc/switch-library/pedals-and-paddles.md) it. 

Is also available with a [filter](/ddc/switch-library/pedals-and-paddles/filtered-curves.md).
{% endtab %}

{% tab title="Example" %}
`void brake(int analogChannel, int releasedValue, int fullyPressedValue)`

For a potentiometer on analog channel 3 it could look like this:

`brake(3, 0, 1023);`
{% endtab %}

{% tab title="Requirements" %}

* None

{% endtab %}
{% endtabs %}

# Agent Instructions: Querying This Documentation

If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter:

```
GET https://dahl-design.gitbook.io/ddc/switch-library/pedals-and-paddles/brake-throttle.md?ask=<question>
```

The question should be specific, self-contained, and written in natural language.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
