Help for a beginner

Hello I am following step by step video on how to get my lcd screen to say Hello World. I have all of my wiring correct but keep getting this error code. I am legit stuck. Thank you.

This is the code i am trying to upload

#include <LiquidCrystal.h>

LiquidCrystal lcd(12, 11, 5, 4, 3, 2);

void setup() {
lcd.begin(16, 2);
lcd.print(“hello, world!”);

void loop() {

This is my error message below

avrdude done. Thank you.

Problem uploading to board. See for suggestions.

This report would have more information with
“Show verbose output during compilation”
option enabled in File → Preferences.

Is your Arduino plugged into COM3? Have you tried other cables?

That weird, in the tools it is not letting me click on port at all. any suggestion? But usually it is already configured to port 3

Assuming this happens with any of possible example sketches (e.g blink):

Check the Windows device manager; you probably have to (re-)install the driver.

try disconnecting the usb and connect it back. Also make sure you selected the right board. If you have the wrong board it will give you unable to download to com portXXX
