Hi, I have an arduino due board. I was having issues and narrowed it down to the following code: int led = 72; // the setup routine runs once when you press reset: void setup() { // initialize the digital pin as an output. pinMode(led, OUTPUT); } // the loop routine runs over and over again …

Bug with LED's???

You would get inverted blinking if you accidentally wired your LED between your output pin and +5V instead of between your output pin and Gnd.
