Finite State Machines Lab $6$

In this lab, we will design a simple state machine that imitates a traffic light. The state machine should

do the following:

Start in the "green" state.

Once switch $S1$ is pressed $($or switched$)$ the state machine should transition to the "yellow"

state for $1$ clock cycle.

After $1$ clock cycle, the state machine should transition to the "red" state and stay there until

switch $S1$ is pressed $($or switched$).$

From the "red" state, after $S1$ is pressed, the state should transition to the "green" state.

Design the state diagram. Once you have the state diagram, create the truth table. From the truth

table, use a K map to design the circuit.

Use a D flip flop to store the state.

Use $3$ different output indicators to indicate the red, yellow, and green states.

Use a switch or push button switch to change the state.

Use the function generator for the clock.

Simulate the state diagram and the circuit using appropriate simulators.

For online students, you will need to move wires back and forth from $+5$ and ground to imitate the clock.

I forget how many LEDs had you order, but you may need to move the connection to the LED between

outputs. ALWAYS MAKE SURE YOU USE A RESISTOR IN SERIES WITH YOUR LED!!! all the work and if possible on paper
