# Feelix Arduino Library

{% hint style="info" %}
The code builds upon [**SimpleFOC** ](https://simplefoc.com)**v2.4.0** by Antun Skuric.\
[**How to install the SimpleFOC library.** ](/uploading-files/simplefoc.md#install-simplefoc-library-using-arduino-ide)
{% endhint %}

> #### If you want to design and upload effects with the Feelix Haptic Design tool, you need to upload the [Feelix Haptic Design Tool Firmware](#feelix-haptic-design-tool-firmware).
>
> #### If you want to write your own code or use exported effects from feelix you need to upload the [Arduino Library for Exported Effects](#arduino-library-for-exported-feelix-effects).

## Feelix Haptic Design Tool Firmware

Download the Feelix Core Firmware to connect with the Feelix Design Tool.

## Arduino Library for Exported Feelix Effects

After you exported effects in Feelix, you can use the FeelixEffect library to import them in your code. *You can no longer connect with Feelix when using this library.*

Want to learn about how to embed the effects in your Arduino code? \
Have a look at the [**FeelixEffect library**](/downloads/arduino-library-documentation/effect-functions.md)[ **documentation**](/downloads/arduino-library-documentation/effect-functions.md)

{% hint style="warning" %}
This library **does not work with the Feelix Design Tool.** It only allows you to import and play exported effects created in Feelix.
{% endhint %}

{% hint style="success" %}
Extract this folder and place it in the **Arduino IDE's 'libraries' directory** to access the example sketches from the File menu. Be sure to **remove any older versions** of the library first.
{% endhint %}

{% hint style="info" %}
Follow these [**instructions**](/uploading-files/setting-up-stm32.md) when **uploading to STM32** for the first time.
