Design and implement a basic stamp$-$based circuit that would simulate the working of two sets of traffic

lights at an intersection. Here is the sequence of events:

a$.$ When the program starts, all traffic lights will be red for $2$ seconds.

b$.$ The green lights for the left arrow and East$-$West traffic will turn on$.$

c$.$ The left arrow will go to amber and then red.

d$.$ After $2$ seconds $($to clear the intersection$),$ the W$-$E light will go green.

e$.$ After a while, the $W-E$ and $E-$W lights will go to amber and then red together.

f$.$ After $2$ seconds $($to clear the intersection$),$ the N$-$S and S$-$N lights will go green together.

g$.$ After a while, the $N-S$ and $S-N$ lights will go to amber and then red together.

h$.$ The green pedestrian light will turn on after two seconds from traffic being stopped on red in that

direction and turn off two seconds before the traffic is allowed to pass on green in that direction.

i$.$ The pattern will repeat again starting at point $($a$)$ above.

Please make the circuit function in a similar manner to a real$-$life traffic light. That is$,$ there should be some

delay between turning ON the Red light for one street and turning ON the Green light for the other street

such that the intersection is cleared of any traffic. There is a total of $17$ LEDs, six on the east side, three on

the west side, and three on the north, three on the south side, and two pedestrian lights. You can wire the

N$-$S together. Please arrange the lights physically on your board as shown below. No flickering or pauses

between light changes. There should not be any time when one light in a particular direction is not on$.$
