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.
