How to control brushless esc using sliders?

#define BLYNK_PRINT Serial
#include <ESP8266WiFi.h>
#include <BlynkSimpleEsp8266.h>
#include <Servo.h>
#include <Blynk.h>

char auth [] = “BiM28uxFGJVc5iS3kpT7F4Wg-Ad5D9DF” ;

char ssid [] = “polnep” ;
char pass [] = “elektronika” ;

int slider;
BLYNK_WRITE(V0)
{
int pinvalue = param.asInt();

}

Servo m1;
Servo m2;
Servo m3;
Servo m4;

void setup()
{
// Debug console
Serial.begin(115200);

Blynk.begin(auth, ssid, pass);

m1.attach(D5); //Pins are attatched to the D5,D6,D7,D8 pins of the NODEMCU which produces pwm//
m2.attach(D6);
m3.attach(D7);
m4.attach(D8);

// You can also specify server:
//Blynk.begin(auth, ssid, pass, “blynk-cloud.com”, 8442);
//Blynk.begin(auth, ssid, pass, IPAddress(192,168,1,100), 8442);

}

void loop() {
Blynk.run();
Serial.print(slider);
Serial.println();
m1.write(slider);
m2.write(slider);
m3.write(slider);
m4.write(slider);

}

My advice would be to edit your post, using the pencil icon at the bottom, and give it a sensible (short) title.
You should then provide some detailed text which describes the hardware you are using, the issues you are encountering, and any other relevant information that will allow other community members to make sense of your post and understand what it is that you are asking.
