And i'm getting a lot of errors.

piz help thx you

FYI I do not take credit for this project.

If you don't take responsibility for the project, what is your part in it?

BTW, cod, I like halibut.

i got the project off line and i'm modifying it for a school project. and i mean code.

That code is garbage and has no chance of compiling.
Where on the internet did you download it? Do you have a link?

Things like this are the reason it could never work:-

piezoHigh const int = 10; // imposed pin which will sound the piezo with high notes
.
rispostaEsatta int = 0; // imposed a variable to contain the correct answer to questions
.
16753245 houses: PowerSwitch = 0;
.
lcd.print ( 'Difficulty');
.
    }
    Else
    {
.
analogWrite (piezoLow, 500);

Hi,
Welcome to the forum.
What is your electronics, programming, arduino, hardware experience?
Do you have all the libraries that the sketch needs?
What is it supposed to do?
What do you want it to do?
What model arduino are you using?
What version IDE are you using?

Tom.... :slight_smile:

This is ware i got the code. I'm using a Arduino Uno just started using about a month to go.

Do you have the three libraries installed?
.

Yes I believe I do. But just to make sure what libraries do I need?

Nate2177:
Yes I believe I do. But just to make sure what libraries do I need?

You don't need all three libraries. "IRremoteInt.h" is automatically included by the "IRremote.h" header file.

You need "IRremote" and "LiquidCrystal". "LiquidCrystal" is included with the IDE, but you need to separately install "IRremote".

I don't know exactly where you downloaded the copy of the code that you posted, I couldn't find it.
I've attached the version I found, but I still had to add the library includes at the top. They were omitted.
This version compiles OK for me. (Too large to post, so I had to attach it.)
