In this tutorial, we will learn how to use GPIO pins of the ESP32 devkit with LED blinking examples using Arduino IDE. Whenever any beginner starts learning about any microcontroller-based development board, Experts always recommend beginners to start with an LED blinking example which is also kn...
ESP32 WiFi Library (Arduino IDE) By default, the ESP32 WiFi library is already built-in the Arduino Core for ESP32, and no need for external library installation. The ESP32 WiFi library provides the fundamental operations that you’d need in any Wi-Fi-based application. However, additional...
Installing ESP32 library in Arduino IDE and upload code When you install the ESP32 add-on in Arduino IDE,FreeRTOS librarywill be installed by default. ESP32 Dual Core Introduction As mentioned before, the ESP32 module consists of two powerful 32-bit microprocessors which make it a dual-core...
