In this example, you will use your Ethernet Shield and your Arduino to send and receive text strings via the UDP protocol (Universal Datagram Packet). You'll need another device to send to and from. The Processing sketch included at the end of the code will send to and receive from your Arduino running this example.

==Hardware Required==

* Arduino or Genuino Board
* Arduino Ethernet Shield

==Circuit==

The Ethernet shield allows you to connect a WizNet Ethernet controller to the Arduino or Genuino 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.

/*
UDPSendReceiveString:
This sketch receives UDP message strings, prints them to the serial port
and sends an "acknowledge" string back to the sender

A Processing sketch is included at the end of file that can be used to send
and received messages for testing with a computer.
