I am brand new to arduino, I was following a guide on how to make a door lock, and I keep running into this error message

Problem uploading to board. See Upload – Arduino Help Center for suggestions.

This report would have more information with
"Show verbose output during compilation"
option enabled in File -> Preferences.

Did you go to the Help Center link in the error message? Did you try the suggestions there?

That error message usually means that there is a communication problem between the PC and the Arduino board.

Did you choose the right serial port in the Tools, Ports menu? Is your USB cable good? Is your board an Uno?

The USB cable you use make sure it is not just charging cable and that it supports data

The program that you write your code in ("IDE") needs to know 3 things:

  1. Which type of board you're compiling for (because they can have different processors and thus need different instructions) - so be sure to click on Tools -> Board and select the right one.

  2. It needs to know where to find your board - so when it's plugged in click on Tools -> Port and make sure there's a tick next to Com "X".

  3. For some boards there are two different versions of the bootloader - so under Tools -> processor try all the options one at a time.

Did that help?

Yes! Thank you so much

Excellent - glad we could help! Thanks for letting us know.
