traffic control circuit

i am designing traffic control circuit, operating at 5v dc, and 200mA. the circuit must control the time for each signal light output by the light bulb; 16 seconds for red, 12 for green, and 4 for amber. and while the red light is on, a two seven segment display counts down the remaining time for the signal. i need a schematic capture and simulaion results.

I doubt anyone is going to do this for you without some effort on your part.

I smell college work. . .

We don't mind helping you but we won't do all of the work for you. Please post what you've already done including any ideas you've had and we might be able to make some suggestions. If you've got completely no idea then may be it's your lecuturer's fault and it isn't right that you make him/her look good by cheating and copying from the Internet.

I agree with the others.

You won't learn much by having us do the work for you.

Make an attempt, post it and we'll advise.
