# D-2 Connect Speaker

Your Photon kit includes a small speaker that can produce tones or play simple music (note by note).

In this step, your team will connect the speaker to your Photon circuit board using the breadboard.

You'll need these components:

* Speaker
* 2 jumper wires (use different colors to help identify them)

[​Follow these instructions explaining how to connect the speaker](https://docs.idew.org/code-internet-of-things/references/physical-outputs/speaker). The speaker can be connected to any I/O pin capable of PWM, but connect it to the **D1** pin (which will be **different** from the wiring diagram).

## 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, and the optional `goal` query parameter:

```
GET https://docs.idew.org/code-internet-of-things/tutorials/create-security-system/4.2-connect-speaker.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

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.
