I'm trying to build this circuit(the first one) for my traffic lights, but it's not working in real life. It works in KTechLab on my computer but not a real breadboard. What's happening is that both LEDs stay on and don't cycle.
The only thing I did different was that I substituted 47K ohm resistors for the 100K. I tested all the individual components and they all work.
