so, i am curently working on a project that requires arduino to connect with node mcu. but everytime i compile the code it turns out to be an error. can someone explain what i did wrong ? it will be so helpfull because the deadline is this saturday, thanks in advice!

heres the code

#include <Wire.h>
#include <LCD.h>
#include <LiquidCrystal_I2C.h>
#include <SoftwareSerial.h>
#include <Servo.h>   //servo library
Servo servo; 
SoftwareSerial s(3,4);

const int  en = 2, rw = 1, rs = 0, d4 = 4, d5 = 5, d6 = 6, d7 = 7, bl = 3;
const int i2c_addr = 0x27;
LiquidCrystal_I2C lcd(i2c_addr, en, rw, rs, d4, d5, d6, d7, bl, POSITIVE);
   
int trigPin = 5;    
int echoPin = 6;   
int servoPin = 7;
int led= 10;
long duration, dist, average;   
long aver[3];   //array for average
int data;

void setup() { 
    lcd.begin(16,2);
    s.begin(9600);      
    Serial.begin(9600);
    servo.attach(servoPin);  
    pinMode(trigPin, OUTPUT);  
    pinMode(echoPin, INPUT);  
    servo.write(0);         //close cap on power on
    delay(100);
    servo.detach(); 
} 

void measure() {  
 digitalWrite(10,HIGH);
digitalWrite(trigPin, LOW);
delayMicroseconds(5);
digitalWrite(trigPin, HIGH);
delayMicroseconds(15);
digitalWrite(trigPin, LOW);
pinMode(echoPin, INPUT);
duration = pulseIn(echoPin, HIGH);
dist = (duration/2) / 29.1;    //obtain distance
}

void sensor() {  
  for (int i=0;i<=2;i++) {   //average distance
    measure();               
   aver[i]=dist;            
    delay(10);              //delay between measurements
  }
 dist=(aver[0]+aver[1]+aver[2])/3;    

if ( dist<10 ) {
//Change distance as per your need
 servo.attach(servoPin);
  delay(1);
 servo.write(0);  
 delay(800); 

        for (int i=0;i<=2;i++) {   //average distance
            measure();               
           aver[i]=dist;            
            delay(10);              //delay between measurements
          }
         dist=(aver[0]+aver[1]+aver[2])/3;    
        
        if ( dist<10 ) {
        //Change distance as per your need
         servo.attach(servoPin);
          delay(1);       
         servo.write(150);    
         delay(800);
         servo.detach();      
        }
Serial.print(dist);
}}

void baru(){
  s.write("s");
    data=s.read();
    if (data == 1){
        lcd.clear();
        lcd.setCursor(0,0);
        lcd.print(" MINYAK JELANTAH");
        lcd.setCursor(0,1);
        lcd.print("   KOSONG  0%   ");
        }
     if (data == 2){
        lcd.clear();
        lcd.setCursor(0,0);
        lcd.print(" MINYAK JELANTAH");
        lcd.setCursor(0,1);
        lcd.print("   TERISI 25%   ");
        }
     if (data == 3){
        lcd.clear();
        lcd.setCursor(0,0);
        lcd.print(" MINYAK JELANTAH");
        lcd.setCursor(0,1);
        lcd.print("   TERISI 50%   ");
        }
      if (data == 4){
        lcd.clear();
        lcd.setCursor(0,0);
        lcd.print(" MINYAK JELANTAH");
        lcd.setCursor(0,1);
        lcd.print("   TERISI 75%   ");
        }
      if (data == 5){
        lcd.clear();
        lcd.setCursor(0,0);
        lcd.print(" MINYAK JELANTAH");
        lcd.setCursor(0,1);
        lcd.print("   PENUH 100%   ");
        }
        
    Serial.println(data);
}

void loop() {
    measure();
    sensor();
    baru();
}

and heres the error

Go back into the IDE, press Ctrl-T to format and post back here, what you've got is unreadable.

the posted code compiles for me using the Arduino IDE and Tools->Board Arduino Uno

suggest the IDE is not configured properly
