Hi Everyone, Here I have a project to turn the pump On/Off based on sensors reading an show the pump condition on Blynk. However, I want to add a feature to control the pump using Blynk itself. Can anyone guide me… Here is the condition:
‘’’
if ( forceReading2>1000 ) {

  digitalWrite(PUMP_PIN, HIGH); // Turn the pump on

  //notification.notify("Pump is On!"); // Send a notification that the pump is on

  Blynk.virtualWrite(V3,1);

 // Blynk.notify("Pump is turned on!");

  Blynk.logEvent("pumpon","Pump is turned ON !!");

  Blynk.virtualWrite(V4,0);  

  delay(80000);  



  Blynk.virtualWrite(V4,1);

  tone(BUZZER_PIN, 1000, 10000); // Generate a 1000 Hz tone

  digitalWrite(PUMP_PIN, LOW);

  Blynk.virtualWrite(V3,0);

  delay(10000);

  Blynk.virtualWrite(V4,0);

  delay(10000);      

   

  }

else {

  digitalWrite(PUMP_PIN, LOW); // Turn the pump off

  digitalWrite(BUZZER_PIN, LOW); // Turn the buzzer off

  Blynk.virtualWrite(V3,0);

  Blynk.virtualWrite(V4,0);

}

Delays are a bad thing when you are planning to use Blynk with your projects. You should avoid them at all cost. You should be using timeout to get the same functionality of delay.

To control the pump from Blynk you can study the example of “Sync physical button”.
