Arduino Tutorial : Sending and Receiving String via UDP

Project description

DETAILS 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 Processingsketch included at the end of the code will send to and receive from your Arduino running this example. Step 1: What You Need? 1 x Arduino Board ( Arduino UNO used in this tutorial) 1 x Arduino Ethernet Shield 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…
