I need to implement a pedestrian crossing into my two way traffic light system. It uses 555 timer for pulse and a 74393 as a counter
I don't know how you could implement a button that would pause the circuit in a state(red in North-south & green in east-west.) While another timer counts down for a pedestrian and then the traffic lights go back to their normal timings?

hi 10,
Post a circuit or diagram of your system so far, so that we can see how to add these changes.

Remember to say you are discussing the UK traffic control system.
