Problem to push data with arduino uno

Need Help With My Project
1

Hi guys, I created a project where I get the temperature and humidity and I would like to send the app but I can not in any way. Would you be kind enough to help me? thanks. This is the code I use:

#include <dht11.h>
#include <Wire.h>
#include <LCD.h>
#include <LiquidCrystal_I2C.h>

#include <SoftwareSerial.h>
SoftwareSerial SwSerial(10, 11); // RX, TX
#define BLYNK_PRINT SwSerial
#include <BlynkSimpleSerial.h>

char auth[] = "MY TOKEN";

LiquidCrystal_I2C lcd(0x27, 2, 1, 0, 4, 5, 6, 7, 3, POSITIVE); // Addr, En, Rw, Rs, d4, d5, d6, d7, backlighpin, polarity

float temperatura;  
int lettura;  
int pinSensore = 0;

dht11 DHT;
#define DHT11_PIN 2

void setup()
{
    analogReference(INTERNAL);
    Serial.begin(9600);

    Blynk.begin(auth);
}


void loop()
{

    Blynk.run();
    
    lettura = analogRead(pinSensore);
    temperatura = lettura / 9.31;
    Serial.println(temperatura);
    
    lcd.setCursor(0,0);
    lcd.print("Temper.:");
    lcd.setCursor(9, 0);
    lcd.print(temperatura);
    
    int chk;
    Serial.print("\t");
    chk = DHT.read(DHT11_PIN);
    Serial.print(DHT.humidity);
    Serial.print("\t");
    
    lcd.setCursor(0,1);
    lcd.print("Umidita':");
    lcd.setCursor(10, 1);
    lcd.print(DHT.humidity);
    lcd.setCursor(12, 1);
    lcd.print("%");
    
    delay(5000);

    temp();
}

void temp()
{

   lcd.clear();
   lcd.print("Invio a Blynk");
   Blynk.virtualWrite(6, DHT.humidity);
   lcd.setCursor(0,1);
   lcd.print(DHT.humidity);

   delay(2000);
   loop();
}

I tried to put it in the app widget Gauge with input V6 and also a value display but nothing

To start, you don’t need the loop( ); call at the end of your temp( ) function. Functions called from the main loop( ) will automatically return to the main loop( ) to the same line it was called from (or the line after). Also, maybe try just writing to Blynk with a very simple program (no lcd, serial.println, or long delays). Then add them back and see when it breaks.

  1. which widget do you use to display data? I would recommend using either value display or gauge

  2. Check the example sketch from the library called PushData - this is exactly what you need.
