➢ Second press b -> 0.5s-> c -> 0.5s-> d -> 0.5s-> a -> 0.5s->e
➢ Third press c -> 0.5s-> d -> 0.5s-> a -> 0.5s-> b -> 0.5s->e ➢ Fourth press d -> 0.5s-> a -> 0.5s-> b -> 0.5s-> c -> 0.5s->e ➢ Fifth press: Same as the First press.
➢ Sixth press: Same as the Second press.
◼ Standard of Grading:
1. Connect all the LEDs and button to the proper ports.
2. The LEDs must work, as the figure shows above.
3. Write a macro named “delay” for blinking for 0.5s.
