Hi,
as discussed earlier today (http://arduino.cc/forum/index.php/topic,117867.0.html) there seems to be a bug in the eeprom_clear
example file as it is posted on the website (http://arduino.cc/en/Tutorial/EEPROMClear) and shipped with the IDE.
Should be fixed by inserting pinMode(13, OUTPUT);
By the way, is there any bugtracking system to report cases like this one?
Best regards
