If you wired a say 10k ohm resistor from pin 13 to ground the problem would go away, or set the pin to output mode and output LOW in your setup function
Hello everybody,I just received my UNO yesterday. I tried the blink example and it works without any problems. I then tried the fade example - the LED on pin 9 fades as it should, but the on-board LED (pin 13) is always on. It is the same with other examples as well (AnalogReadSerial, even BareMinimum).Is this normal behavior? Shouldn't the on-board LED be turned off?I am able to switch it off by adding the DigitalWrite(13, LOW) in the example sketch.
