  Serial.print("V1 Slider value is: ");
  Serial.println(pinValue);
  if(pinValue==1){
  digitalWrite(LEDpin, HIGH);   
  delay(1000);                       
  digitalWrite(LEDpin, LOW);   
  delay(1000);}

How to blink led continuous using BLYNK_WRITE(V0)?

with a blynk timer

StartBlinkLed = timer.setInterval(1000L, BlinkLed); //blink every 1 s


BLYNK_WRITE(V0)
{
  int pinValue = param.asInt(); 
  Serial.print("V1 Slider value is: ");
  Serial.println(pinValue);
  if(pinValue==1){
timer.enable(StartBlinkLed ); // Turn BlinkLed Timer  on;
}else{
timer.disable(StartBlinkLed ); // Turn BlinkLed Timer off;
     }
}

void BlinkLed(){
If (Ledflag==0){
digitalWrite(LEDpin, HIGH);  
}else{
 digitalWrite(LEDpin, LOW); 
   }
}
```

“How to type a question in the body of the post instead of a long run on sentence in the title…” oh well, that failed :frowning:

At least there are lots of ways to Blynk LEDs :stuck_out_tongue:
