Example Code for Arduino UNO
Below is an example of how to use the Ethernet Pro with an Arduino UNO to create a simple web server:
#include <SPI.h>
#include <Ethernet.h>
// MAC address and IP address for the Ethernet Pro
byte mac[] = { 0xDE, 0xAD, 0xBE, 0xEF, 0xFE, 0xED };
IPAddress ip(192, 168, 1, 177); // Set a static IP address
// Initialize the Ethernet server on port 80
EthernetServer server(80);
void setup() {
// Start the Ethernet connection
Ethernet.begin(mac, ip);
// Start the server
server.begin();
Serial.begin(9600);
Serial.println("Server is ready at IP: ");
Serial.println(Ethernet.localIP());
}
void loop() {
// Listen for incoming clients
EthernetClient client = server.available();
if (client) {
Serial.println("New client connected");
boolean currentLineIsBlank = true;
while (client.connected()) {
if (client.available()) {
char c = client.read();
Serial.write(c); // Print received data to Serial Monitor
// Respond to HTTP GET request
if (c == '\n' && currentLineIsBlank) {
client.println("HTTP/1.1 200 OK");
client.println("Content-Type: text/html");
client.println("Connection: close");
client.println();
client.println("<!DOCTYPE HTML>");
client.println("<html>");
client.println("<h1>Welcome to Ethernet Pro Web Server!</h1>");
client.println("</html>");
break;
}
if (c == '\n') {
currentLineIsBlank = true;
} else if (c != '\r') {
currentLineIsBlank = false;
}
}
}
// Give the client time to receive the data
delay(1);
client.stop();
Serial.println("Client disconnected");
}
}
Best Practices
- Use a regulated power supply to avoid damaging the Ethernet Pro.
- Ensure proper grounding to minimize noise and interference.
- Use a static IP address for reliable network communication.
- Avoid long SPI cables to reduce signal degradation.
Troubleshooting and FAQs
Common Issues
No Ethernet Connection
- Cause: Incorrect wiring or configuration.
- Solution: Double-check the SPI connections and ensure the Ethernet cable is securely connected.
Unable to Obtain IP Address

- Solution: Use a static IP address in your code.
High Power Consumption
- Cause: Overloading the Ethernet Pro with peripherals.
- Solution: Use an external power supply if the current exceeds the microcontroller's capacity.
Intermittent Connectivity
- Cause: Poor-quality Ethernet cable or network interference.
- Solution: Replace the cable and ensure the network environment is stable.
