Please help me to debug this programme

richipearl

I wrote the following code to make a seven digit segment display number from 1 to 9 continuously but while compiling the arduino ide write error, too many argument  to function turnOn

 

 

byte ledPin[7]={2,3,4,5,6,8,9};

#define buttonPin 11

int no = 0;

int pushButton = 0;

void setup() {

  for(int a = 0;a < 7;a++){

  pinMode(ledPin[a],OUTPUT);

  }

  pinMode(buttonPin,INPUT_PULLUP);

  turnOn();

}

  // put your setup code here, to run once:

 

void turnOn()

{ 

  pushButton = digitalRead(buttonPin);

 

  {

    if (pushButton == LOW)

    no++;

    delay(200);

  }

{

switch(no)

  {

    case 1:

      digitalWrite(ledPin[0],LOW);

      digitalWrite(ledPin[1],HIGH);

      digitalWrite(ledPin[2],HIGH);

      digitalWrite(ledPin[3],LOW);

      digitalWrite(ledPin[4],LOW);

      digitalWrite(ledPin[5],LOW);

      digitalWrite(ledPin[6],LOW);

      break;

    case 2:

     digitalWrite(ledPin[0],HIGH);

     digitalWrite(ledPin[1],LOW);

     digitalWrite(ledPin[2],HIGH);

     digitalWrite(ledPin[3],HIGH);

     digitalWrite(ledPin[4],HIGH);

     digitalWrite(ledPin[5],HIGH);

     digitalWrite(ledPin[6],LOW);

     break;

    case 3:

      digitalWrite(ledPin[0],HIGH);

      digitalWrite(ledPin[1],HIGH);

      digitalWrite(ledPin[2],HIGH);

      digitalWrite(ledPin[3],HIGH);

      digitalWrite(ledPin[4],LOW);

      digitalWrite(ledPin[5],HIGH);

      digitalWrite(ledPin[6],LOW);

      break;

    case 4:

    digitalWrite(ledPin[0],LOW);

    digitalWrite(ledPin[1],HIGH);

    digitalWrite(ledPin[2],HIGH);

    digitalWrite(ledPin[3],LOW);

    digitalWrite(ledPin[4],LOW);

    digitalWrite(ledPin[5],HIGH);

    digitalWrite(ledPin[6],HIGH);

    break;

   case 5:

   digitalWrite(ledPin[0],HIGH);

   digitalWrite(ledPin[1],HIGH);

   digitalWrite(ledPin[2],LOW);

   digitalWrite(ledPin[3],HIGH);

   digitalWrite(ledPin[4],LOW);

   digitalWrite(ledPin[5],HIGH);

   digitalWrite(ledPin[6],LOW);

   break;

  case 6:

    digitalWrite(ledPin[0],HIGH);

    digitalWrite(ledPin[1],HIGH);

    digitalWrite(ledPin[2],LOW);

    digitalWrite(ledPin[3],HIGH);

    digitalWrite(ledPin[4],HIGH);

    digitalWrite(ledPin[5],HIGH);

    digitalWrite(ledPin[6],HIGH);

    break;

  case 7:

    digitalWrite(ledPin[0],HIGH);

    digitalWrite(ledPin[1],HIGH);

    digitalWrite(ledPin[2],HIGH);

    digitalWrite(ledPin[3],LOW);

    digitalWrite(ledPin[4],LOW);

    digitalWrite(ledPin[5],LOW);

    digitalWrite(ledPin[6],LOW);

    break;

  case 8:

      digitalWrite(ledPin[0],HIGH);

      digitalWrite(ledPin[1],HIGH);

      digitalWrite(ledPin[2],HIGH);

      digitalWrite(ledPin[3],HIGH);

      digitalWrite(ledPin[4],HIGH);

      break;

  case 9:

    digitalWrite(ledPin[3],HIGH);

    digitalWrite(ledPin[4],LOW);

    digitalWrite(ledPin[5],HIGH);

    digitalWrite(ledPin[6],HIGH);

    break;

    }

    }

}

void loop()

{

  for (int b = 0;b < 10;b++)

  {

    turnOn(b);

    delay(500);   

  }

 

  }

 

 

// put your main code here, to run repeated

    your turnOn() function expects 0 parameters, but you pass it 1 parameter: turnOn(b)

    Thanks for your contribution but can you please explain more

  • 0 in reply to richipearl

    There's not a huge amount the explain. Only one line needs to change. turnOn(b); need to become turnOn();

     

    void loop()
{
  for (int b = 0;b < 10;b++)
  {
    turnOn();
    delay(500);   
  }
}

     

    Of course, once it compiles then it may not do exactly what you were expecting. It's best to tackle this one step at a time and work through the bugs. That's the only way you'll get an understanding of what you're trying to do.

    Rachel,

     

    You have defined your function as: void turnOn()

     

    The initial void says that it will not return anything which is fine because your function will just turn on  some LED segments and does not need to return any value.

     

    However, the empty brackets say that it does not any arguments. This is not correct because you need to pass a number to turn on the desired segments. So, you have to put something in the brackets to indicate tthat you will be passing an argument. In your case, you are passing an integer value, so you may write 'int b' there.

     

    Hope this helps,

    Faiz

    Looks like you have an opening brace in the wrong place as well:

     

    void turnOn()
{  
  pushButton = digitalRead(buttonPin);
  
  {    
    if (pushButton == LOW)
    no++;
    delay(200);
  }

     

     

    perhaps should be:

     

    void turnOn()
{  
  pushButton = digitalRead(buttonPin);
   
  if (pushButton == LOW)
  {
    no++;
    delay(200);
  }

    Thanks so much to everyone's contribution

    byte ledPin[7]={2,3,4,5,6,8,9};// declare pins to led

    my code is now working
