I am doing a traffic light design control circuit, so the light will change from red to yellow (for 3s) to green(for 12s) then to yellow(3s) , my question is how do when the light is green, how do I make it green for 12 s before turning yellow again. I was given a clock with 3s cycle.
Do I have to use J-K flip flop or counter ? Is there a way not to use it ? Because we wont be taught them until next week .
