merhaba,
arduino ide de kodu derlediğimde herhangi bir hata vermemektedir fakat esp8266ya kodu attığımda seri port ekranında semboller çıkmakta ve çalışmamaktadır. farklı bir kod attığımda esp8266 çalışıyor sorun yok fakat aşağıdaki kodu attığımda bu şekilde seri port ekranında gözüküyor

    {
      Serial.println(F("Failed to read from DHT sensor!"));
      return;
    }
    timeClient.update();

    String day = daysOfTheWeek[timeClient.getDay()];
    String formattedTime = timeClient.getFormattedTime();
    String formattedDayTime = String(day) + String(",") + String(formattedTime);
    String fireHumid = formattedDayTime   + String(": ") + String(h) + String("%");           //Humidity integer to string conversion

Baudrate hızına bir bak.

"Serial.println()" satırından sonra "delay(250);" gibi bir bekleme koyup dener misiniz?
