------------------------------------------------------------------------------- Arduino Duemilanove As per image http://arduino.cc/en/uploads/Main/ArduinoDuemilanove.jpg ------------------------------------------------------------------------------- Blink Compiler failure. Using the default 'Blink' sketch from http://arduino.cc/en/Tutorial/Blink The arduino produced a solid unblinking LED. Details in forum topic "LED Blink Program Weirdness" http://arduino.cc/forum/index.php/topic,68512.0.html This seems to be caused by a bug in the compiler, causing the 'Delay()' function to fail when no global variable is defined (non-zero) and used. Details of bug in forum topic "Arduino Mega 1280 delay() turbocharged" http://arduino.cc/forum/index.php/topic,49900.0.html However the 'Blink' stetch distributed with teh arduino software v0022 works perfectly fine as it defines a uses a variable LEDPin for the output pin attached to the LED (13 for the on board LED) -------------------------------------------------------------------------------
