#include <SPI.h>   // needed for Arduino versions later than 0018
#include <Ethernet.h>
#include <EthernetUdp.h> // UDP library from: bjoern@cs.stanford.edu 12/30/2008

// Enter a MAC address and IP address for your controller below.
// The IP address will be dependent on your local network:
byte mac[] = {
  0xDE, 0xAD, 0xBE, 0xEF, 0xFE, 0xED
};
IPAddress ip(192, 168, 0, 3);
unsigned int localPort = 8888; // local port to listen on

// An EthernetUDP instance to let us send and receive packets over UDP
EthernetUDP Udp;
IPAddress remoteIP(192,168,0,102);
unsigned int remotePort = 8888;

void setup() {
  // start the Ethernet and UDP:
  Ethernet.begin(mac, ip);
  Udp.begin(localPort);
  Serial.begin(9600);
}

void loop() {
  Udp.beginPacket(remoteIP, remotePort);
  // output the value of each analog input pin
  for (int analogChannel = 0; analogChannel < 6; analogChannel++) {
    int sensorReading = analogRead(analogChannel);
    Udp.write("analog input ");
    Udp.print(analogChannel);
    Udp.write(" is ");
    Udp.print(sensorReading);
    Udp.write("\n");
  }
  Udp.endPacket();
  delay(100);
}

Menerima Menggunakan nc

ifconfig eth0 192.168.0.102

nc -ul 8888

Akan keluar

analog input 0 is 1023
analog input 1 is 1023
analog input 2 is 995
analog input 3 is 992
analog input 4 is 1010
analog input 5 is 967

Menerima Menggunakan python

Source python

import socket
import time

UDP_IP = "192.168.0.102"
UDP_PORT = 8888

sock = socket.socket(socket.AF_INET, # Internet
                     socket.SOCK_DGRAM) # UDP
sock.bind((UDP_IP, UDP_PORT))

while True:
    data, addr = sock.recvfrom(1024) # buffer size is 1024 bytes
    print time.strftime('%X %x %Z'), "\n", data
