Installation

To get started with Arduino, it’s easiest to install Arduino’s own development environment, the Arduino IDE.

Arduino IDE

The Arduino IDE is a development environment for Arduino. With it you can write code and upload it to a microcontroller. The IDE includes built‑in examples and a serial monitor to inspect the microcontroller’s output.

Installation

  • Go to the Arduino website.
  • Download the Arduino IDE for your operating system.
  • Install the Arduino IDE on your computer by following the installation steps of the setup.

Configuration

To use ESP32 boards from within the Arduino IDE you first need to install the ESP32 board support package. Follow these steps:

  • Open the Arduino IDE.
  • Go to Files > Preferences.
  • Under the Preferences tab, click the button next to Additional Boards Manager URLs.
  • In the text field that opens, add the following URL: 
    https://espressif.github.io/arduino-esp32/package_esp32_index.json
  • Click the OK button to save the settings.

You can now install the ESP32 boards.

ESP32 boards install

  • Navigate to Tools > Board > Boards Manager.
  • Search for ESP32 and click the Install button to install the ESP32 boards (make sure to choose the Espressif Systems variant).
