Printing an integer to an LCD

Neat method!

Did you mean digits[4] instead of char[4]? it yelled at me about that

Here's what I have now:

char* intToChar(int value) {
  char digits[5] = {' ',' ',' ',' ',' '};
  while(value > 0) {
     digits[4]=(char)((value%10)+48);
     value=value/10;
     digits[3]=(char)((value%10)+48);
     value=value/10;
     digits[2]=(char)((value%10)+48);
     value=value/10;
     digits[1]=(char)((value%10)+48);
     value=value/10;
     digits[0]=(char)((value%10)+48);
  }
  return digits;
}

...

lcd.print(intToChar(1));

The error it gives me is:
In function 'void loop()':
error: invalid conversion from 'char*' to 'int

I tried
lcd.print((char)intToChar(1));
and
lcd.print((char*)intToChar(1));

But no luck :frowning:

Thanks!!
