Hello Peoples. I am pretty new here and new to all this circuitry stuff. I am in a competition and I have to build a Stoplight Mechanism (basically a traffic light). I need to know how i can build it WITHOUT using electronic timer chips or any of the sort. Attached here is a PDF of the rules. I need help, I am Totally lost.
P.S. I am only in Grade 9 and the price must not exceed $24.99
