## Components

- **WIZnet W5500** x 1 ([docs](https://docs.wiznet.io/Product/Chip/Ethernet/W5500))
- **Arduino UNO** x 1 ([docs](https://www.farnell.com/datasheets/1682209.pdf))

WIZnet parts: W5500 ([Datasheet](https://docs.wiznet.io/Product/Chip/Ethernet/W5500/datasheet?utm_source=maker&utm_medium=project&utm_campaign=w5500), [product hub](https://maker.wiznet.io/products/w5500/))

## Article

The used SPI to connect W5500 and Arduino Uno. By using the library (Ethernet2), it could easily created a communication with chip. The user used the library with the reference source code, he created a HTTP webserver to show DHT11 and light sensor results
