Basically, you've to attach each led into an arduino digital pin and set to output.

How it works:

An array of arrays for all values 0,1,2,...,16 coded in binary count:

{0,0,0,0},{0,0,0,1},{0,0,1,0},­{0,0,1,1},...{1,1,1,1}

So you only need a loop to set leds on/off according to values on the array (each position on the array sets leds status).
