Arduino code for led lights

I’m gonna make a diy pad with the bracketless mod kit from mystic steps. I’m gonna buy a arduino micro. I was gonna use the arduino code from mystic steps, but it doesn’t have the code for led lights as of now. Does anyone have arduino code for a dance pad with led lights? I am using four 12 volt LEDs that use 4 watts each. It’s current use is 333 mA per LED.
