a) Your system should have three external LEDs and an external button.

b) LED1 will be on for 1 sec, after which LED2 will be on for 2sec. Then they will both be off for 2 sec. This cycle will repeat forever.

c) LED3 is toggled by the pressing and releasing the button. Nothing should happen when the button is pressed but on the release of the button.

d) LED1 and LED2 will also go off when the button is released, thereby resetting the cycle in (b) above.

Use the flowchart model in Proteus to implement the system. Note that the system should blink the internal LED every 3sec.
