Full code
#include <WiFi.h>
const char* ssid = "YOUR_WIFI";
const char* password = "YOUR_PASSWORD";
void setup() {
Serial.begin(115200);
WiFi.begin(ssid, password);
while (WiFi.status() != WL_CONNECTED) {
delay(500);
Serial.print(".");
}
Serial.println(WiFi.localIP());
}
void loop() {}How it works
This lesson matches the page title and gives a clean starting point for this exact example.
Common mistakes
