/*•	
Na PORT D priključi 8 LED diod.
•	Na pin A0 priključi potenciometer. Prebrano vrednost potenciometra mapiraj tako, da bo najmanjša vrednost 0 in največja 8.
•	Vrednost potenciometra določa kateri element seznama se bo izpisal na PORT D. 
•	Seznam določi tako, da bo pri vrednosti potenciometra 1 svetila 1 LED, pri vrednosti 2 bo svetila samo LED 2, pri 3 bo svetila samo LED 3… , pri 8 bo svetila samo LED 8.
•	Nalogo reši s funkcijami pinmode(), digitalRead() in digitalWrite().
