title: Redeclared as different kind of symbol in Arduino
body: <p>I'm currently working on a school project. I want the servo to move according to the number of coins selected. I keep getting the error " 'void servoOne()' redeclared as different kind of symbol " I know this has been asked but I'm not sure how to fix this. </p>
  
  <p>Here is my code.</p>
  
  <pre><code>#include &lt;LiquidCrystal.h&gt;
  #include &lt;Keypad.h&gt;
  #include &lt;Servo.h&gt;
  
  Servo servoOne;

  int piso=0;
  int lima=0;
  int sampu=0;
  
  String input="";
  String remlast = "";
  
  LiquidCrystal lcd(A0, A1, A2, A3, A4, A5);//RS,EN,D4,D5,D6,D7
  
  
  const byte Rows= 4; //number of rows on the keypad i.e. 4
  const byte Cols= 3; //number of columns on the keypad i,e, 3
  
  //we will definne the key map as on the key pad:
  
  char keymap[Rows][Cols]={
    {'1', '2', '3'},
    {'4', '5', '6'},
    {'7', '8', '9'},
    {'*', '0', '#'}
  };
  
  byte rPins[Rows]= {3,4,5,6}; //Rows 0 to 3
  byte cPins[Cols]= {7,8,9}; //Columns 0 to 2
  
  Keypad kpd= Keypad(makeKeymap(keymap), rPins, cPins, Rows, Cols);

    // put your setup code here, to run once:
  lcd.begin(20,4);
  servoOne.attach(10);
  }
