# IoT Blocks

The Internet of Things (IoT) connects your devices together through the internet, where data can be shared and exchanged. With built-in Wi-Fi, Codey Rcoky can connect to the internet to realize its IoT functionality, such as obtaining data of the weather. Use IoT blocks to explore cutting-edge stuff with Codey Rocky.

## Add IoT Blocks

### 1. Make sure "Codey" is selected and click "+" in the Blocks area.

## Have Some Fun

Let's try out the new IoT blocks. We will make Codey report weather.

### 1. Drag a when Codey starts up block from the Events category to the Scripts area.

### 3. Drag a if () then () block from the Control category. Add a Wi-Fi connected? block from the IoT category to the condition. Codey Rocky needs to join a Wi-Fi network to obtain weather data.

### 4. Drag a show () block from the Looks category, and wrap it up with the if () then () block. We want Codey to show weather data, so we need to add a weather in () block from the IoT category. Type in a city name. In this example, we type in "Shenzhen" and choose the drop-down list.

## 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://learn.pakronics.com.au/primary/codey-rocky-ai-robot/tutorials/iot-blocks.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.
