4 Way Traffic Light

Description

The fundamental idea of this simple electronic project is to control the traffic. It can be used to avoid vehicular collisions and traffic jams. This project is just a one-way traffic controller, although it can be further modified as well. The project will work in a way, it provides instruction to the driver whether to drive through the intersection or yield at the intersection. The timing of the glow of certain lights totally depends upon the 555 timer’s pulse, which we can control via the Potentiometer so if you want to change the time of glow, you can do so by varying the potentiometer, having the responsibility for the timing.

This traffic light kit is made with the help of counter IC, which is mainly used for Sequential Circuits. We can also call it Sequential Traffic Lights. Sequential Circuits are used to count the numbers in the series. Coming to the working principle of Traffic Lights, the main IC is 4017 counter IC which is used to glow the Red, yellow and green LED respectively. 555 timer acts as a pulse generator providing an input to the 4017 counter IC.
