.

You should identify the codes and laws that prohibit such activities in your state.

Ladder diagram image of the full solution before simulation is started.
 Testing scenarios with images. Here you will show pictures of the LOGO program
during simulation of a particular scenario. Write an explanation for each step of
the scenario showing why such input sequence causes the output sequence
shown. Include images of the LOGO simulation which demonstrate that indeed
you have observed these test scenarios.
