This is a little cute game cube that is controlled only by simple laser pointer. The game itself is very simple – you have to shoot falling dots on LED matrix screen with laser pointer as long as you can to gain more points. During time dots fall faster and faster what makes it really challenging to beat previous records.
But probably the most interesting part in its game is laser pointer detection technology. As sensing device it uses LED matrix itself. To do so there are two measurement techniques (reverse bias and direct measurement) used where one detects the row and second column at which LED laser is pointed. Game is controlled by Arduino mini board.
