Arduino IDE Installation and ESP32 Setup Guide

This guide provides step-by-step instructions for installing the Arduino IDE and configuring it for ESP32 development.

Step 1: Install Arduino IDE

Begin by installing the Arduino IDE software. Follow the on-screen prompts during the installation process.

License Agreement

You will be presented with the GNU Lesser General Public License. Please review the terms and click "I Agree" to accept and proceed with the installation.

Installation Options

Select the components you wish to install. Common options include:

Arduino software
USB driver
Start Menu shortcut
Desktop shortcut
Associate .ino files

After selecting your components, click "Next".

Installation Folder

Choose the destination folder for the Arduino IDE installation. The default location is typically C:\Program Files (x86)\Arduino. Click "Install" to begin the file copying process.

Windows Security Prompt

During installation, a "Windows Security" prompt may appear asking for permission to install the "Arduino USB Driver" published by "Arduino srl". If this prompt appears, click "Install" to allow the driver installation. If no such prompt is displayed, you can safely ignore this step.

Installation Completion

Once the installation is finished, click "Close". An Arduino icon should now be visible on your desktop.

Step 2: Extract ESP32 Core Files

Locate the downloaded compressed file, typically named arduino-esp32.zip.

Use a file compression utility (such as 2345 HaoYa) to extract the contents of the arduino-esp32.zip file.

Extraction Destination: Extract the files to the Arduino hardware directory. The standard path is C:\Program Files (x86)\Arduino\hardware. You may need to manually create the arduino-esp32 subfolder within the hardware directory if it does not already exist.

After successful extraction, the hardware folder should contain subfolders like arduino, arduino-esp32, and tools.

Step 3: Configure Arduino IDE for ESP32

Open the Arduino IDE application.

Navigate to the 'Tools' menu, then select 'Board'. From the dropdown list, choose the specific ESP32 development board you are using. The example shown highlights "ESP32F", but you can select from a wide range of ESP32 boards like "ESP32 Dev Module", "NodeMCU-32S", etc.
