"Can you help me with a college assignment? I need to build a physical prototype of the GENIUS memory game with a potentiometer for difficulty adjustment (light speed) and a 7-segment display to visualize the level (0 ~ 9) at which the game is operating. I need 5 buttons, one of which is used to restart the game while returning it to level zero. It should indicate the game's difficulty level:
0: easiest -> lights stay on for a longer time 9: hardest -> lights flash more rapidly, and a potentiometer to change the game's difficulty level. I tried but couldn't succeed."
