First, let us take into account that a traffic light is used to indicate the pass or pair of cars or pedestrians, in this case we will make a system for cars since we will have two neighboring streets and if we cannot, a traffic light can cause a traffic accident, for which the The design of this project is made with very basic components but at the same time effective.

This project is made to make a basic traffic light and see how this system works, for which we will require a circuit that gives us square pulses to activate the different outputs of the CD4017 IC, this integrated is a sequencer, that is, at each pulse it will activate in sequence a different output.

The circuit that will deliver the pulses will be an integrated NE555 in astable configuration. We already know that this circuit will allow us to deliver a train of pulses to its outputs by configuring 2 resistors and a capacitor with a high time and a low time, so we will obtain different signals of start times either a fast time or a slower or longer time.

This project can also put RELE outputs to activate 220VAC lights, thus becoming a more professional project and a REAL system to take it to our locations where they do not obtain this system for the control of cars or pedestrians.
