Oh, OK, 330 will be fine. It's a current-limiting resistor for the LED. With 330 it might not be as bright, but actually 330 is sort of my "standard" resistor for most 5mm LEDs, many of them are quite bright with 330 ohms at 5V.
Good luck digging out. The storm has moved out here, it will be a cold and clear night with lows around 5°F. We had maybe 4" or 5" of snow, so nothing all that remarkable here.
Good weather to stay in and play with microcontrollers, enjoy!
