範例

#include <WiFi.h>

char ssid[] = "yourNetwork";     // 無線網路的 SSID
int status = WL_IDLE_STATUS;     // 無線網路的狀態

byte mac[6];                     // 存放 MAC 位址的陣列

void setup()
{
 Serial.begin(9600);

 status = WiFi.begin(ssid);

 if ( status != WL_CONNECTED) {
    Serial.println("Couldn't get a wifi connection");
    while(true);
  }
  // 如果成功連線，印出 WiFi Shield 的 MAC 位址
  else {
    WiFi.macAddress(mac);
