Need Help With My Project

Hi, i have some error in my project
3. Add details :
My hardware: esp8266
• Samsung A14(Android 13, One UI Core 5)
• Indonesia
• Blynk at version 1.3.2

Here’s my code:



#define BLYNK_PRINT Serial
#define BLYNK_TEMPLATE_ID "TMPL6Yyn_YkCD"
#define BLYNK_TEMPLATE_NAME "MQ2 ESP8266"
#define BLYNK_AUTH_TOKEN "------"

#include <ESP8266WiFi.h>
#include <Blynk.h>

char auth[] = BLYNK_AUTH_TOKEN;
char ssid[] = "WiFiID";
char pass[] = "mypass";

BLYNK_WRITE (V0) {
  digitalWrite(D0, param.asInt());
}

void setup() {
  Serial.begin(9600);
  Blynk.begin(auth, "blynk.cloud", 8080);
  // put your setup code here, to run once:

}

void loop() {
  // put your main code here, to run repeatedly:
  int sensorValue1 = digitalRead(D2);
  int sensorValue2 = digitalRead(D3);
  int sensorValue3 = digitalRead(D4);

  Blynk.virtualWrite(V1, sensorValue1);
  Blynk.virtualWrite(V2, sensorValue2);
  Blynk.virtualWrite(V3, sensorValue3);

  delay(100);
  Blynk.run();
}

The issues:

What’s Blynk_h for?

@mnafif24 Please edit your post, using the pencil icon at the bottom, and add triple backticks at the beginning and end of your code and your compiler error message so that they display correctly.
Triple backticks look like this:
```

Copy and paste these if you can’t find the correct symbol on your keyboard.

just a wrong suggestion by the compiler. ignore it. Blynk_h is the include guard macro.

your include should be #include <BlynkSimpleEsp8266.h>

Done. Thx, Mr.Pete

No, you only did the code, not the compiler error message
