Design a control circuit to energize 3 lights (red, amber, green) . The red light will turn on as soon as a Start button is pressed. Two seconds later, the amber light will turn on,. The green light will turn on 2 seconds after the amber light. After the green light is on for 2 ms, all lights should go off. This cycle should repeat until a STOP button is pressed. Draw the sequence bar chart for this circuit as...

Design a finite state machine for a traffic light at the intersection of north-south traffic and east-west traffic. The light can be red, green or yellow. Assume a 30 second clock. Assume that the light will change only if a car is coming in the other direction. If cars are in both north-south and east-west, the light will change from one direction to the other. What are the machine states? What are the inputs? What are the outputs? Draw state...

Q1 (30 pts) Design a state-based PLC program to control a motor. The system specification is as follows. • Press a normally open push button, the motor will start. Motor stop will stop after 5 minutes or a normally close push button is pressed. . When the motor is running, a read light is ON. When the motor is stopped, a green light is ON. Use the "Fail Safe" concept, i.e., if the wire of...

Designing a Traffic Light Controller [50 pts] [Your originality, thinking method and execution would be graded] In Gotham city, traffic lights have three outputs as Red (R), Yellow (Y) or Green (G). Let's assume you're given a microchip with clock input 0.2 Hz. As you know.cars can travel when the light is Green and should not pass the traffic light when the light is Yellow or Red. We are asked to design the traffic light controller in the busiest road...

Write the following program to be executed on the FPGA board. 1. Write a VHDL model for a code detector as shown in the Figure. The keypad is used to unlock a door. Pressing the start button followed by the sequence red-green-red-blue unlocks the door, no other sequence can open the door. Assume the clock is slowed down and each pressing of a button is detected once. For example when red is pressed it is only detected as pressed for...
