Project 3 – Traffic Lights

You are now going to create a set of traffic lights that will change from green to red, via amber, and back again, after a set length of time using the four-state UK system. This project could be used to make a set of working traffic lights for a model railway or for a child's toy town. If you're not from the UK, you can modify the code and colors to make them work like the traffic lights in your own country. First, though, make the project as it is and change it once you know how it works.
