Project Description

This version attempts to get an IP address using DHCP. An IP address can be assigned via DHCP when Ethernet.begin(mac) is called. Be careful, when using the DHCP extensions, sketch size increases significantly.

Step 1: What You Need?

1 x Arduino Board ( Arduino UNO used in this tutorial)
1 x Arduino Ethernet Shield

Software Required

– A telnet server

– Alternatively, Processing has a ChatServer example that works well for this purpose

Step 2: Build Your Circuit.

The Ethernet shield allows you to connect a WizNet Ethernet controller to the Arduino boards via the SPI bus. It uses pins 10, 11, 12, and 13 for the SPI connection to the WizNet. Later models of the Ethernet shield also have an SD Card on board. Digital pin 4 is used to control the slave select pin on the SD card.
The shield should be connected to a network with an ethernet cable. You will need to change the network settings in the program to correspond to your network.

Step 3: Upload The Code.

–  Details are explained! You just do step by step!
