Comibining arduino sketch with blynk sketch

Hey i am hard Begineer in this IOT field and electronics
i am making my project about dual axis solar tracking
using component:
arduino uno
2 x SG 90 servo motor
4 x LDR

Here is my arduino sketch Which is working properly individually

////////////////////////////////////////////////////////////////////////////////////////

#include<Servo.h>

// 180 horizontal MAX
Servo horizontal; // horizontal servo
int servoh = 180; // 90; // stand horizontal servo
int servohLimitHigh = 180;
int servohLimitLow = 0;

// 65 degrees MAX
Servo vertical; // vertical servo

int servov = 45; // 90; // stand vertical servo
int servovLimitHigh = 150;
int servovLimitLow = 30;

// LDR pin connections
// name = analogpin;

int ldrlt = 0; //LDR top left - BOTTOM LEFT <--- BDG
int ldrrt = 1; //LDR top rigt - BOTTOM RIGHT
int ldrld = 2; //LDR down left - TOP LEFT
int ldrrd = 3; //ldr down rigt - TOP RIGHT

void setup()
{ Serial.begin(9600);
// servo connections
// name.attacht(pin);
horizontal.attach(9);
vertical.attach(10);
horizontal.write(180);
vertical.write(45);
delay(3000);
}

void loop() 
{ int lt = analogRead(ldrlt); // top left
int rt = analogRead(ldrrt); // top right
int ld = analogRead(ldrld); // down left
int rd = analogRead(ldrrd); // down right
// int dtime = analogRead(4)/20; // read potentiometers
// int tol = analogRead(5)/4;
int dtime = 10; int tol = 50;
int avt = (lt + rt) / 2; // average value top
int avd = (ld + rd) / 2; // average value down
int avl = (lt + ld) / 2; // average value left
int avr = (rt + rd) / 2; // average value right
int dvert = avt - avd; // check the diffirence of up and down
int dhoriz = avl - avr;// check the diffirence og left and rigt

Serial.print(avt);
Serial.print(" ");
Serial.print(avd);
Serial.print(" ");
Serial.print(avl);
Serial.print(" ");
Serial.print(avr);
Serial.print(" ");
Serial.print(dtime);
Serial.print(" ");
Serial.print(tol);
Serial.println(" ");

if (-1*tol > dvert || dvert > tol) // check if the diffirence is in the tolerance else change vertical angle
{
if (avt > avd)
{
servov = ++servov;
if (servov > servovLimitHigh)
{
servov = servovLimitHigh;
}
}
else if (avt < avd)
{
servov= --servov;
if (servov < servovLimitLow)
{
servov = servovLimitLow;
}
}
vertical.write(servov);
}
if (-1*tol > dhoriz || dhoriz > tol) // check if the diffirence is in the tolerance else change horizontal angle
{
if (avl > avr)
{
servoh = --servoh;
if (servoh < servohLimitLow)
{
servoh = servohLimitLow;
}
}
else if (avl < avr)
{
servoh = ++servoh;
if (servoh > servohLimitHigh)
{
servoh = servohLimitHigh;
}
}
else if (avl = avr)
{
// nothing
}
horizontal.write(servoh);

delay(dtime);
}

Here is my blynk code

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

// You should get Auth Token in the Blynk App.
// Go to the Project Settings (nut icon).
char auth[] = "lCbb6SkIdLPARJdIBY5TSoqQcWwBUaJs";

Servo servo1;
Servo servo2;

BLYNK_WRITE(V2)
{
  servo1.write(param.asInt());
  }
  BLYNK_WRITE(V3){
    servo2.write(param.asInt());
  }

void setup()
{
  // Debug console
  SwSerial.begin(9600);

  // Blynk will work through Serial
  // Do not read or write this serial manually in your sketch
  Serial.begin(9600);
  Blynk.begin(Serial, auth);
  servo1.attach(9);
  servo2.attach(10);
}
void loop()
{
  Blynk.run();
}

//////////////////////////////////////////////////////////////////////////////////////////////

servo 1 and servo 2 are controlled properly through blynk app with two slider widget Individually

what i am trying is …

i want to control the servo motor through blynk app and by supplying light by torch manually simultaneously…

PLZ help me to combine this two sketches to control simultaneously

It will be more thankful to those whos answered to me

Sry for my bad english!!!

Please edit your post to wrap your code in triple backticks like this:

```
Code goes here...
```

Thanks for suggestion Man!!!
i learned new thing from you!!!

Firstly, start by reading this:

Also, using the serial connection isn’t a viable solution for a long term project. You might be better using a an ESP8266 based device such as a NodeMCU, although it depends on who you’re driving your servos.

You’re unlikely to find anyone on this forum who will re-write your code for you, and you need to learn yourself anyway.
