I know little about programming, and have a specific question.

My code is receiving an error, and I am using a tutorial. The tutorial is located at this webpage: http://blog.tinyenormous.com/2009/09/30/17-arduino-nikon-ir-intervalometer-code/

The code that I need help with is as follows:

void snap(){
    int i;
    digitalWrite(PIN_STATUS,  1);  
          for(i=0;i”);
          sequence[i] = (sequence[i] * FREQ) / (intervalle * 1000);
          Serial.println(sequence[i]);
      }
}

The error:

stray '/' in program
    for(i=0;i”);

source of your error

Thank you, now how can I fix it? I am not familiar with this syntax, however, I know lua, and sometimes it gets confusing.

I thought you're going off a tutorial. Here's instructions on for loop http://arduino.cc/en/Reference/For

I am, but the tutorial code is incorrect, so could you help me fix this one line of code?

Here is exactly how to do it:

for(i=0; i<100; i++){
     sequence[i] = (sequence[i] * FREQ) / (intervalle * 1000);
     Serial.println(sequence[i]);
}

The i<100 means it would repeat 100 times. Which is repeat until i is no longer smaller than 100. i++ means add one every time the for() function runs.

Read more about the for function:

Thank you, but now I get the error intervalle was not declared in this scope.
If needed, here is the full code:

intervelle is declare in loop(), but you are trying to use it in snap(). It should be made global.

Like I said, I have no coding experience besides lua, and so I will need help making this global. What do I need to change?

Beatz1337: Like I said, I have no coding experience besides lua

But you have Google, don't you?

Try googling C++ global scope to see some simple examples.

Ok, and if it gets moved to become a global variable, will it still be able to change as the pot changes?

Beatz1337: will it still be able to change as the pot changes?

It doesn't do that now.
