Arduino IDE Setup

The following setup guide page will take you through configuring Arduino IDE for the Adafruit ESP32-S2 TFT Feather. Before continuing with this guide, ensure that you have tested connecting this board to your local WiFi network.

• If you are using a different Arduino (or Arduino-compatible) board with this project, please follow the hardware-specific instructions to set up your hardware before continuing with this guide.

The Adafruit IO Arduino library allows you to write Arduino code to interface with Adafruit IO.

To install the Adafruit IO Arduino library, open the Arduino IDE and navigate to the Manage Libraries... option in the Sketch -> Include Library menu.

In the Library Manager, search for Adafruit IO Arduino

The Library Manager will prompt you, asking you to install missing dependencies. Click "Install All".

Get your Adafruit IO Username and Active Key

To connect your device to Adafruit IO, you will need your Adafruit IO credentials. To obtain these, navigate to io.adafruit.com and click the key icon on the header.

A pop-up should appear displaying your Adafruit IO username and active key. Keep these two credentials handy for the next step.

Create Feed(s) for Project

Feeds are the core of the Adafruit IO system. A feed holds data and meta-data that you have sent to Adafruit IO. 

For more information about feeds, visit the Adafruit IO Basics: Feeds guide:

Creating a Feed on Adafruit IO is a very simple process. From any page on Adafruit IO, click on the Feeds link on the header.

On the Feeds page, click the New Feed button.

A pop-up will appear, fill out the following name and description for this feed:

Name the feed analog and optionally set its description. Click Create.

You'll see your new feed appear on the feed page, underneath the "Default" group.
