Hi,  
I can see that you already have created a writer that you called output.

So now, you just need to replace your print and println statements by output.print and output.println

Missing line break at the end of each line

Try to print ”\n“ at the end of each line

You missed an output.print("/n") line13 of your function called function.

Also please correctly format you code using ctrl+t on processing before posting it here.

In notepad:

Is the display of line breaks activated?

See menu View

Or try to look at your file with another program like WordPad or MS Word

Are you using appropriate current limiting resistors?  
An LED exploded in one of our labs at work with low voltages (5V); it can happen.  
Always wear safety glasses when working on projects like this.

Hello,

Typo there…

output.print("/n") will print /n

There are the different possible outputs I used testing:

```auto
        //Text file: // Output:
        //output.print("\r"); // CR
        //output.write("\r"); // CR 
        //output.print("\n"); // LF
        //output.write("\n"); // LF
        //output.write("\r\n"); // CRLF        
        //output.print("\r\n"); // CRLF
        //output.print(); // Error! Won't run.
        //output.println(); // CRLF
        //output.print(""); // no output!
        //output.write(""); // no ouput! 
        //output.print("/n"); // /n
        //output.print(":)"); // :)

```

I used Notepad++:  
[https://notepad-plus-plus.org/](https://notepad-plus-plus.org/)  
and select “View \> Show Symbol \> Show all Characters” to see the LF and CR characters (otherwise hidden from view).
