# How to find code for my hardware?

Does my hardware work with Blynk? Which example code should I use with my hardware?

{% hint style="warning" %}
This documentation is for the LEGACY version of Blynk platform which is no longer supported and will be shut down. 

You can sign up for the current version of Blynk platform [here](http://blynk.cloud/dashboard/register).

The new mobile apps can be downloaded from [App Store](https://apps.apple.com/us/app/blynk-iot/id1559317868) and [Google Play](https://play.google.com/store/apps/details?id=cloud.blynk\&hl=en\&gl=US).

The actual Blynk documentation is [here](https://docs.blynk.io/).
{% endhint %}

Blynk works with hundreds of hardware models and connection types. We prepared **Blynk Examples Sketch Builder** that allows you to create example code for your hardware.

### ⚙️ Find a full list of all supported hardware [here](https://github.com/blynkkk/blynkkk.github.io/blob/master/SupportedHardware.md) <a href="#find-a-full-list-of-all-supported-hardware-here" id="find-a-full-list-of-all-supported-hardware-here"></a>

☝️ **Before moving forward, make sure you have Blynk Library properly installed.**<br>

### Find the example code for your hardware <a href="#find-the-example-code-for-your-hardware" id="find-the-example-code-for-your-hardware"></a>

[Open Blynk Examples Builder](http://examples.blynk.cc/)![](https://uploads.intercomcdn.com/i/o/19400959/c0c34377e80478a4a02354ca/examples2.gif)

1. Choose your board
2. Choose your Connection (WiFi, Ethernet, Bluetooth, USB...)
3. Browse through examples and choose the one you need
4. Sketch Builder will create a sketch for you.
5. Copy the whole code and paste it to Arduino IDE

### Input your Auth Token <a href="#input-your-auth-token" id="input-your-auth-token"></a>

In the example sketch find the line:

```
char auth[] = "YourAuthToken";
```

Change it with your own Auth Token (it should be in your email inbox after you created the Project in the Blynk app.

Now this line should look similar to this:

```
char auth[] = "53e4da8793764b6197fc44a673ce4e21";
```

🔥 Flash the example code to your hardware

### Done! Now go and try other examples: <a href="#done-now-go-and-try-other-examples" id="done-now-go-and-try-other-examples"></a>

### Find the example code for your hardware <a href="#find-the-example-code-for-your-hardware" id="find-the-example-code-for-your-hardware"></a>

This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## 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.blynk.io/en/~/revisions/ALsZL4ielzatIAwAwHQo/legacy-platform/legacy-articles/getting-started.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.
