    • 1. Example Code for Arduino-Blink

    This article provides a comprehensive guide to setting up the Arduino IDE for Beetle ESP32 microcontroller, including manual installation of the CH340 driver if necessary, configuration of FireBeetle-ESP32 board URL, and installation of the FireBeetle-ESP32 library. Once the development environment is set, users can implement the Blink code using the default LED pin D9. The code involves initializing the pin as an output and creating a loop function to turn the LED on and off with a one-second delay. The article ensures users have successfully installed necessary components, verified board selection, and connected the microcontroller via USB to proceed with coding.
