Need a little help with coding error

Hello. Im trying to figure out what is wrong with the below code. Spend the last hour looking and no luck.

#include <TimerOne.h>
#include <Bounce2.h>
#include <Keyboard.h>

//I have used pin 10 on my board for my switch
const int inputPin = 10;

Bounce button0 = Bounce();
Bounce button1 = Bounce();
Bounce button2 = Bounce();

Bounce button5 = Bounce();

Bounce button[6] = {
  Bounce(),
  Bounce(),
  Bounce(),
  Bounce(),
  Bounce(),
  Bounce()
};

Error states that: setupLeds’ was not declared in this scope

Thank you in advance for the help

Do an auto format (ctrl-t or Tools, Auto Format) on the code and you will see that the curly bracket (}) to close the loop() function is missing.

Thanks for this, but after auto format I receive this one:

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

Did you add the missing curly bracket?

         //HPIM Incident
         Keyboard.print("I will check this one.");
         Keyboard.press(KEY_RETURN);
         Keyboard.releaseAll();

         delay(500);

      }

   }
}  // added

Thanks for this, but after auto format I receive this one:

Auto Format does not fix problems but it tidies up code and helps show problems with layout.

Where is the end of the loop() function ?

To expand on what UKHeliBob said. Here is the portion of your code after auto format (before being fixed). Note how void CheckKeys() is indented. That means that the IDE thinks that void CheckKeys() is part of the loop() function.

        delay(500);
      }
   }

   void CheckKeys()
   {
      for (int i = 0; i < 4; i++)

The same portion of code after adding the missing }. Note that void CheckKeys() is no longer indented? That means that the void CheckKeys() is now a function on its own outside of loop().

        delay(500);
      }
   }
} // added

void CheckKeys()
{
   for (int i = 0; i < 4; i++)

As advised I have added the missing curly bracket and:

This is a combination of two codes, and trying to merge them in one working and....

Post the modified code. We can't help with code that we cannot see. I added the curly bracket and the code compiles for me (IDE 1.8.5, Leonardo).

All done. Stupid me put the reverse bracket. Thank you very much for the prompt help :slight_smile:
