Example code

/*
Controlla i relè tramite WiFi.
*/
#include <ESP8266WiFi.h>

const char* ssid = "SSID";
const char* password = "PASSWORD";

// Verifica sul datasheet per i pin specifici del modulo
void setup() {
  Serial.begin(115200);
  WiFi.begin(ssid, password);
  while (WiFi.status() != WL_CONNECTED) {
    delay(500);
    Serial.print(".");
  }
  Serial.println("WiFi connected");
}

void loop() {
  // Verifica sul datasheet per le istruzioni specifiche del modulo
}

Mini project

Create an outdoor light control system that turns on and off via a mobile app. Set a timer to automatically turn on the light at night.

Common mistakes
