Hello,
We have been assigned an assignment to set up an Arduino. I messed up with the most important with this question.
Problem - Figure below shows the intersection of a highway with a local street.. Vehicle detection sensors are placed along lanes B and D ( highway ) and lanes A and C ( Street ). These sensor outputs are LOW (0) when no car is present and HIGH (1) when a car is present. The intersection traffic light is to be controlled according to the following logic:
- The east - west (E - W) traffic light will be green whenever both lanes D and B are occupied.
- The E - W light will be green whenever either D or B is occupied but lanes A and C are not both occupied.
- The north - south (N - S) light will be green whenever both lanes A and C are occupied but D and B are not both occupied.
- The N - S light will also be green when either A or C is occupied while D and B are both vacant.
- The E - W light will be green when no vehicles are present.
Q1. Using sensor outputs A, B, C, and D as inputs, design a logic circuit to control the traffic light. There should be two outputs, N - S and E - W that go HIGH when the corresponding light is to be green.
Q2. Write down the Truth Table for this circuit.
Q3. Write down the Some - of - Product form for this circuit without any simplification.
Q4. Simplify your logic expression ob tained in Q3. Justify each step down using the multivariable theorems taught during the lectures.
Q5. Use a K - map as an alternative tool to simplify the logic expression achieved in Q3.
Q6. Describe how your circuit would operate if the sensor located at section C is stuck HIGH.
My Arduino works but I can't make the logic work. Can you guys please help me with Q2 of this assignment? I did make a truth table but the teacher says it is wrong and I have no where to get extra support. Thank you! If you are generous, can you help me with other questions too?
