Arduino – Ping Servers with Arduino Uno with WiFi

You can ping servers by domain name or IP address and use the response time as a value for a variable.

Functional Parts in the Project:

• Arduino WiFi Rev 2 – https://store.arduino.cc/usa/arduino-uno-wifi-rev2

#include <WiFiNINA.h>

char ssid[] = "test";
char pass[] = "";

int status = WL_IDLE_STATUS;

String hostName = "www.google.com";
IPAddress localServer(172, 16, 42, 5);

int googleResult;
int serverResult;

void setup() {

  Serial.begin(9600);

  while (status != WL_CONNECTED) {
    Serial.print("Attempting to connect to Network named: ");
    Serial.println(ssid);
    status = WiFi.begin(ssid, pass);
    delay(10000);
  }

  Serial.print("SSID: ");
  Serial.println(WiFi.SSID());
  IPAddress ip = WiFi.localIP();
  Serial.print("IP Address: ");
  Serial.println(ip);
}

void loop() {

  googleResult = WiFi.ping(hostName);
  serverResult = WiFi.ping(localServer);

  Serial.print("Google.com: ");
  Serial.println(googleResult);
  Serial.print("Local Server: ");
  Serial.println(serverResult);
  delay(2000);
