Pwm pin connection using ESP-12E module

hi every one can any one help me for my project with ESP 12E module by PWm for fading a light intensity.

Im able to write the code for PWM but in the blynk app which pin i have to select ???

Blynk.run();
  {
   analogWrite(LedPin, 0);   
  delay(1000);              
  analogWrite(LedPin, 255);   
  delay(1000);              
  analogWrite(LedPin, 512);  
  delay(1000);

it depends on which pin the LED is connected to.

If it connected to say D2 then set LedPin = D2;

also, as others will no doubt point out, you need to avoid such big delays in the main loop…

ok
let me check
