I have some questions about this example from the Refence page.
// 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, 1, 177);
unsigned int localPort = 8888; // local port to listen on
// An EthernetUDP instance to let us send and receive packets over UDP
EthernetUDP Udp;
void setup() {
// start the Ethernet and UDP:
Ethernet.begin(mac,ip);
Udp.begin(localPort);
}
void loop() {
Udp.beginPacket(Udp.remoteIP(), Udp.remotePort());
Udp.write("hello");
Udp.endPacket();
}
------------- Question 1 -----------------
First what does this line exactly do?
IPAddress ip(192, 168, 1, 177);
What is the first word IPAddress doing?
------------- Question 2 -----------------
About the library functions Udp.remote and Udp.remotePort.
Udp.beginPacket(Udp.remoteIP(), Udp.remotePort());
Where in the example above should I set this values for my remote Arduino?
