Make a four way traffic light signal project using IC 555

This simple project demonstrates the working of a traffic light signal. It uses a 555 timer IC and a decade counter to build this four way traffic light circuit. 

The concept of this project is very simple. The ten stage DECADE COUNTER have a memory of ten, that means, it can count upto ten pulses. So for every peak at clock, the counter admits it as an event and remembers it. The number of events that counter memorized outputted by corresponding pin.
