Part $01-$ State Diagram:

$1.$ Based on the above introduction, draw the state diagram for the traffic light circuit. North$-$South will have a similar sequence as well as East$-$West. Two$-$way traffic flow.

$2.$ Hint:

a$.$ Determine the number of states based on the required sequence of Red $\backslash (\backslash$gg $\backslash )$ Yellow $\backslash (\backslash$gg $\backslash )$ Green. Assign binary values for each state $(\backslash (2^\{$n$\}\backslash )).$

b$.$ Green light will stay for $3$ ticks and Yellow for $1$ tick and back to Red.

c$.$ Use one control input.

d$.$ Use smart art or any appropriate drawing tool to create your state diagram and place it inside the box. Make sure to properly label them
