Use BLYNK_WRITE(V200)

Need Help With My Project

I’ve never has to use BLYNK_WRITE_DEFAULT(), but according to he who knows everything, its not quite the way you’ve described:

In the example @Gunner gives, it seems that request.pin returns the pin that triggered the BLYNK_WRITE_DEFAULT() callback:

BLYNK_WRITE_DEFAULT() {
  int pin = request.pin; // determines what vPin is triggering this response
  if (param.asInt() == 1) {
   Serial.print("Button on Virtual Pin ");
   Serial.print(pin);  // Display the number of the vPin
   Serial.println(" is pressed");
  } else {
    // Do something, or nothing, when button is OFF
  }
}

so if you had different code that ran for V200, V201, V202 then you’d need to use a series of ‘if’ statements, or a Select Case statement.
