## Article

**# Overview**

This project shows you how to send WS2812B data file through Ethernet.

**# Hardware**

I made a matrix display board using 64 pcs of WS2812B leds.

**# Software (Transmitter - Host)**

I have developed a Windows-based GUI program to use the led data easily. This application can control each and whole leds and also send pre-written RGB led script file through Ethernet.

**# Software (Receiver - Slave)**

If GUI program send a file to W5100S-EVB-Pico through Ethernet UDP packet, W5100S-EVB-Pico receive until getting whole data. after then execute a file on W5100S-EVB-Pico.
