Does Aurduino have any built in error state indicators when a program is running?
I have a program that while it is running, randomly the LED connected to pin 13 will blink.
I did not setup pin 13 as an OUTPUT or INPUT.
I do not believe there is any kind of hardware issue as it does not happen running other programs.


For the moment I am not trying to trouble shoot my program, I am just wanting to know if there is anything running in the background of
the Arduino that might flag errors states.

I am using an Arduino Duemilanove board.

Thanks.

You didn't but the processor has defaults defined on reset.
In the case of Pin13 the boot loader sets it to an output, but on the latest boot loader it resets it to an input.
