## Article

This video showcases a basic embedded application using the **W5500-EVB-Pico** development board. Through **serial communication**, the program outputs runtime information for debugging and observation, while an onboard LED is driven to create a smooth **breathing light effect**.

The demonstration helps viewers understand fundamental concepts such as **UART printing**, **GPIO control**, and **PWM-based LED effects**, making it a good starting point for learning development and peripheral control on the W5500-EVB-Pico platform.
