Basic LED "Blink" not working

I've probably used the most basic blink program. Forgive me as I'm new to Arduino, but I've connect pin 8 to the negative side of a red LED with a 330 ohm resistor(orange-orange-brown) thin connected the positive(long side) of the LED to GND. Using UNO 3.It's not working


Is you LED the wrong way around perhaps?

Sounds like it is.

power to the resistor. to the long pin, then the short pin to the arduino.

blink away !
