Steps for setting up a development environment using Arduino IDE 2.x

This guide outlines the steps for setting up a development environment using Arduino IDE 2.x.

1 - Installing Arduino IDE 2.x

Installation procedure for the integrated development environment (IDE)

This guide outlines the steps for installing Arduino IDE 2.x.

If you already have Arduino IDE 2.x installed, you can skip this section.

Open Arduino official download page in your web browser and download Arduino IDE (2.X.X).

Run the downloaded file and follow the instructions to install Arduino IDE 2.x.

Installation procedure for ESP32 toolchain

This guide outlines the procedure for installing ESP32-specific compilers and libraries compatible with Arduino.

If you already have Arduino core for the ESP32 installed, you can skip this section.

For detailed installation instructions, refer to the official documentation.

Launch Arduino IDE 2.x and open Preferences from the toolbar.

Enter the following URL in the Additional Boards Manager URLs field and click OK:

https://espressif.github.io/arduino-esp32/package_esp32_index.json

Open the Boards Manager from the second icon from the top in the sidebar.

Type “ESP32” in the search box and install the esp32 board definition.

Select esp32, not Arduino ESP32 Boards.
