Exploring Arduino: Arduino + Ethernet + DHCP with EtherTen

introduce

This project shows how to use Arduino UNO as Web Server with IP address from DHCP.

On Etherten based on Wiznet W5100, Arduino that has no static IP address is leased to virtual IP from DHCP server.

hardware

• Arduino UNO
• EtherTen

open source 

• Arduino Ethernet Library
• Arduino DHCP Library
• Example Code

Users only need to change the MAC address. MAC address is unique. There is not same MAC in the world. So, users must change it to what Etherten has.

After running the example code, Ethenet gets IP address and users type it on the web browser ( must connect to PC and Etherten).

Users might be able to see the page as shown below which Arduino Web server provides.
