Traffic Light System by Using Timer Relays

Traffic lights are sets of red, amber, and green lights at the places where roads meet. They control the traffic by signalling when vehicles have to stop and when they can go. Traffic lights can also be referred to as a traffic light.

The timer relays have a fixed time period to switch traffic between different directions. Due to this, the vehicles have to wait for a long time span even if the traffic density is very less.

I use following matterial

1- cardboad

2- timer relays

3- wires/ jumpers

4- tape

5- AC lights

my first step is to wiring this timer relays properly.

next step is to construct its road.

and finally to stand a pole for traffic lights.
