What is wrong here?

Uhh, so here is my code:

#include <LiquidCrystal.h>
#include <DFR_LCD_Keypad.h>
#include <Keyboard.h>


LiquidCrystal lcd(8,9,4,5,6,7); 
DFR_LCD_Keypad keypad(A0, &lcd);


int led=13;
int last_key, key;

void setup()
{
  lcd.begin(16,2);
  lcd.setCursor(0,0);
  lcd.print("PRESS KEYS NOW");
  pinMode(led, OUTPUT);
  delay(1000);
  lcd.clear();
  Keyboard.begin();
}

void loop()
{
  #include "Keyboard.h";
  last_key = keypad.get_last_key();
  key      = keypad.read_key();
  

  if (key != last_key) {
    
    lcd.clear();
    lcd.setCursor(0,0);
    
    switch (key) {
      case KEY_RIGHT:
        lcd.print("RIGHT");
        break;
        
      case KEY_UP:
        lcd.print("UP");
        break;
        
      case KEY_DOWN:
        lcd.print("DOWN");
        break;
        
      case KEY_LEFT:
        lcd.print("LEFT");
        break;

      case KEY_SELECT:
        lcd.print("SELECT");
        Keyboard.print("r");
        digitalWrite(led, HIGH);
        break;
        
      case KEY_NONE:
      default:
        lcd.print("NO KEYS PRESSED");
        lcd.setCursor(0,1);
        lcd.print("PRESS KEYS NOW");
        digitalWrite(led, LOW);
        break;
    }
  }
  delay(10); 
}`

It says that it couldn't find "#include keyboard.h", this is the error message:

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

Anybody know what's wrong?

2

That is what is wrong.

3

Why that? Is my board broken?

4

No, it's the wrong board for the keyboard library.

More detail here.

5

Which board can I use then? Is it compatible with an Arduino Mega?

6

Read the link.

7

But on the list, the Arduino Uno is listed. Why isn't it working then?

8

"while the library is supposed to compile correctly on these architectures, it might require specific hardware features that may be available only on some boards."

9

Hm, Ok.

10

No, I don't know why the Uno is on that list.

11

"This library is compatible with the avr, samd, sam architectures so you should be able to use it on the following Arduino boards:"

They just list all AVR, SAMD, and SAM architecture boards. I think the list is auto-generated based on the library architecture property. The disclaimer below the list covers the fact that not all AVR, SAMD, and SAM boards are compatible.

12

Yeah, it does look that way.
Lazy.
