I need help

I have to see serial monitor on LCD attached to arduino while running Blynk

That can’t be very hard, can it? Catch everything from the serial monitor and output it to the LCD? What have you tried so far?

I ve tried this code but it doesn’t work…
if (Serial.available() ){
// wait a bit for the entire message to arrive
delay(100);
// clear the screen
lcd.clear();
// read all the available characters
while (Serial.available() > 0) {
// display each character to the LCD
lcd.write(Serial.read());
}
