4 Slot machine
With a total of three LEDs, one can now build a small slot
machine, which is otherwise only found in the casino or in
the pub. All three LEDs are connected in series to the adja-
cent ports of the microcontroller. The short connections (cath-
odes) must be reconnected to the lower negative row.
Now all the LEDs are flashing fast, much like the rolls of a
machine turn. The aim of the game is to stop the LEDs with
the button so that all three LEDs light up at the same time
(111). This is the only way to get a jackpot.
