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 well.
