About the control of Servo

Please tell us about the control of Servo.

Control through WiFi is possible.
Press the button to move Servo.
Servo moves but does not come back.

Servo 180 rotation 3 seconds stop 180 rotation reverse
Please tell me this code.

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

Servo servo;

char auth[] = "";
char ssid[] = "Buffalo-G-D658";
char pass[] = "";

void setup()
{
  Serial.begin(9600);
  Blynk.begin(auth, ssid, pass);

  servo.attach(15); // NodeMCU D8 pin
  
 }
  
void loop()
{
  
  Blynk.run();
  
}
BLYNK_WRITE(V1)
{
   servo.write(param.asInt());
   {
  for ( pos = 0; pos < 180; pos += 1 ) {    myservo.write( pos );    delay( 15 );  }  for ( pos = 180; pos > 0; pos -= 1 ) {
    myservo.write( pos );
    delay( 15 );
  }
}

BLYNK_WRITE(V2)
{
  servo.write(180);
}
BLYNK_WRITE(V3)
{
  servo.write(180);
}

I’ve edited your code so that it displays correctly.
In future, when you post code please add:

```cpp

at the top of the code and:

```

at the end of your code, otherwise the code will be deleted.

Pete.
