Arduino uno + esp-01 + lcd (not working)

Using Arduino Displays
1

I used 4 sensor with arduino uno and also connected it to blynk, i also want to display the output in LCD but when i upload the lcd code the its not running, but without the lcd code its running in blynk. what should i do ?

this my code without LCD (this code is running with blynk)

#define BLYNK_PRINT Serial

#define BLYNK_TEMPLATE_ID ""
#define BLYNK_TEMPLATE_NAME ""
#define BLYNK_AUTH_TOKEN ""


#include <OneWire.h>
#include <DallasTemperature.h>
#include <Wire.h>

// Your WiFi credentials.
// Set password to "" for open networks.
const char auth[] = BLYNK_AUTH_TOKEN;

char ssid[] = "";
char pass[] = "";

#include <SoftwareSerial.h>
SoftwareSerial EspSerial(2, 3);  // RX, TX

// Your ESP8266 baud rate:
#define ESP8266_BAUD 9600
OneWire oneWire(4);                   // Pin 2 is used for the OneWire interface
DallasTemperature sensors(&oneWire);  // Pass the OneWire reference to DallasTemperature library

ESP8266 wifi(&EspSerial);
float calibration_value = 22.85;
int phval = 0;
unsigned long int avgval;
int buffer_arr[10], temp;
int temperature;
int turb ;
float ph ;
int tds ;
const int tdsPin = A1;  // Analog input pin for TDS sensor

BlynkTimer timer;

void setup() {
  // Debug console
  Serial.begin(9600);
  delay(10);

  // Set ESP8266 baud rate
  EspSerial.begin(ESP8266_BAUD);
  delay(10);
  
  Blynk.begin(BLYNK_AUTH_TOKEN, wifi, ssid, pass);
    timer.setInterval(1000L, getSendData);
}

void loop() {
  Blynk.run();
    timer.run();

}

void getSendData(){
  // Temperature
  sensors.requestTemperatures();                   // Request temperature readings from the sensor
  float temperature = sensors.getTempCByIndex(0);  // Get the temperature in Celsius

  // Turbidity
  int turbidity = analogRead(A2);
  float turb = turbidity * (5.0 / 1024.0) * 3;

  // pH
  for (int i = 0; i < 10; i++) {
    buffer_arr[i] = analogRead(A0);
  }
  for (int i = 0; i < 9; i++) {
    for (int j = i + 1; j < 10; j++) {
      if (buffer_arr[i] > buffer_arr[j]) {
        temp = buffer_arr[i];
        buffer_arr[i] = buffer_arr[j];
        buffer_arr[j] = temp;
      }
    }
  }
  avgval = 0;
  for (int i = 2; i < 8; i++) {
    avgval += buffer_arr[i];
  }
  float volt = (float)avgval * 5.0 / 1024 / 6;
  ph = -5.70 * volt + calibration_value;

  int tdsValue = analogRead(tdsPin);
  float voltage2 = tdsValue * (5.0 / 1024.0);
  float tds = voltage2 * 1000;  // Convert to TDS value (adjust the conversion factor as per your sensor)


Serial.print("temp: ");
Serial.println(temperature);

Serial.print("turb: ");
Serial.println(turb);

Serial.print("ph: ");
Serial.println(ph);

Serial.print("tds: ");
Serial.println(tds);

Blynk.virtualWrite(V0, temperature);
Blynk.virtualWrite(V1, turb);
Blynk.virtualWrite(V2, ph);
Blynk.virtualWrite(V3, tds);


}

but when i put this code with lcd it's not running also didn't display anything in serial monitor

      Lcd();

}

  lcd.setCursor(0, 0);
  lcd.print("checking ");


Serial.print("temp: ");
Serial.println(temperature);

Blynk.virtualWrite(V0, temperature);
Blynk.virtualWrite(V1, turb);
Blynk.virtualWrite(V2, ph);

}

what should i do ?
