Hello I am new to Arduino and I need some help.

I get the error message : sketch_feb12a.ino: In function 'void loop()':

to the following code:

int timer = 1000;          
int i = 1;

void setup()
 {  for (int thisPin1 = 1;  thisPin1 < 13; thisPin1++)  
    for (int thisPin2 = 13; thisPin2 < 25; thisPin2++)  
    for (int thisPin3 = 24; thisPin3 < 38; thisPin3++)

}}

I can not find the problem.

Thanks for your help!!!

Can you tell us what you're trying to do?
I can't really see a reason for that degree of loop nesting.

Code:

digitalWrite(53; LOW);

Look again.

[Reply #2 on:]

I am trying to run 4 rows of led lamps.
Each led should light up for 1 second and for each led a photo should be taken and i want to control the shutter of the camera differently at each row.

THANK YOU!

post your code with using the code tag function ok btw your code, you are using all your pin in maybe a mega i think
you just use ; in what should be ,

Code:

int timer = 1000;          
int i = 1;

void setup()
 {  for (int thisPin1 = 1;  thisPin1 < 13; thisPin1++)  
    for (int thisPin2 = 13; thisPin2 < 25; thisPin2++)  
    for (int thisPin3 = 24; thisPin3 < 38; thisPin3++)  
    for (int thisPin4 = 37; thisPin4 < 43; thisPin4++)  
 {
    pinMode(thisPin1, OUTPUT);  
    pinMode(thisPin2, OUTPUT);
    pinMode(thisPin3, OUTPUT);
    pinMode(thisPin4, OUTPUT);
    pinMode(51, OUTPUT);
    pinMode(52, OUTPUT);
    pinMode(53, OUTPUT);
}}


void loop()
 {  while (i<2) {i++;
 {  for (int thisPin1 = 1;  thisPin1 < 13; thisPin1++)  
    for (int thisPin2 = 13; thisPin2 < 25; thisPin2++)
    for (int thisPin3 = 24; thisPin3 < 38; thisPin3++)  
    for (int thisPin4 = 37; thisPin4 < 43; thisPin4++)  
   {
    digitalWrite(52, HIGH);
    delay(3000);
    digitalWrite(52, LOW);
 
    digitalWrite(thisPin1, HIGH);
    digitalWrite(53, HIGH);
    delay(100);
    digitalWrite(53, LOW);
    delay(timer);
    digitalWrite(thisPin1, LOW);
 
    digitalWrite(thisPin2, HIGH);
    digitalWrite(53, HIGH);
    delay(100);
    digitalWrite(53, LOW);
    delay(timer);
    digitalWrite(thisPin2, LOW);

    digitalWrite(thisPin3, HIGH);
    digitalWrite(53, HIGH);
    delay(100);
    digitalWrite(53, LOW);
    delay(timer);
    digitalWrite(thisPin3, LOW);

    digitalWrite(thisPin4, HIGH);
    digitalWrite(53, HIGH);
    delay(100);
    digitalWrite(53, LOW);
    delay(timer);
    digitalWrite(thisPin4, LOW);
}}}}

Yes. I am using a Mega Arduino.

Sorry, I did not understand what I should change.

Thanks a lot for your help!!!

[Reply #5 on:]

The errors are being caused by lines like this

Code:

digitalWrite(53; LOW);

I am sure that you can see what is wrong  Using the Tools/Autotidy in the IDE made them stand out immediately, and the error line is highlighted by the compiler anyway.

[Reply #6 on:]

i gave you the edited version ....

Code:

Oh, I see. Thank you very much. It was highlighted, but i did not see the error.

How many for loops are there in this code ?

Code:

    for (int thisPin1 = 1;  thisPin1 < 13; thisPin1++) 
    for (int thisPin2 = 13; thisPin2 < 25; thisPin2++) 
    for (int thisPin3 = 24; thisPin3 < 38; thisPin3++) 
    for (int thisPin4 = 37; thisPin4 < 43; thisPin4++) 
 {
    pinMode(thisPin1, OUTPUT); 
    pinMode(thisPin2, OUTPUT);
    pinMode(thisPin3, OUTPUT);
    pinMode(thisPin4, OUTPUT);
    pinMode(51, OUTPUT);
    pinMode(52, OUTPUT);
    pinMode(53, OUTPUT);
}

Answers from the OP only, please.

[Reply #10 on:]

I do have four rows of leds. And the shutter has to be controlled different at every row.
Is the code wrong? There is no more error code.

Thanks,

S

[Reply #11 on:]

There is no more error code

That only means that the program is syntactically correct, and that the compiler has generated code for the code as written.
It does not necessarily mean that the code will  do what you intended.

Does the code do what you intended?

[Reply #12 on:]

The code is not exaclty wrong, more that it is unusual and unnecessary.
Try this, which as you will see is derived from your code.

Code:

void setup()
{
  int counter =1;
  Serial.begin(9600);

  for (int thisPin1 = 1;  thisPin1 < 13; thisPin1++) 
    for (int thisPin2 = 13; thisPin2 < 25; thisPin2++) 
      for (int thisPin3 = 24; thisPin3 < 38; thisPin3++) 
        for (int thisPin4 = 37; thisPin4 < 43; thisPin4++) 
        {
          counter++;
        }
  Serial.println(counter);
}

void loop() {}

You may be surprised by the number of for loops that have been run. Explain in simple terms what you want those for loops to do.

[Reply #13 on:]

I want to run 4 rows of leds and to every led i want to take a picture. And the shutter time should be different in every row.
Anyway. My code does not work properly.

[Reply #14 on:]

My code does not work properly.

Because it is crap, as others have tried to point out.

If you were to use curly braces for every for loop, you'd see that. It is the nesting of the for loops that is wrong.

This is what you want:

Code:

  for (int thisPin1 = 1;  thisPin1 < 13; thisPin1++)
  {
     pinMode(thisPin1, OUTPUT);
  }
  for (int thisPin2 = 13; thisPin2 < 25; thisPin2++) 
  {
     pinMode(thisPin2, OUTPUT);
  }
  for (int thisPin3 = 24; thisPin3 < 38; thisPin3++) 
  {
     pinMode(thisPin3, OUTPUT);
  }
  for (int thisPin4 = 37; thisPin4 < 43; thisPin4++) 
  {
     pinMode(thisPin4, OUTPUT);
  }

Now, what is the loop() function supposed to do? The nested loops there are probably wrong, too.
