3 Way Traffic Light Circuit Diagram. 3 way light switch circuit wiring diagrams. In the above 3 way switch wiring diagram at each switch the black wire gets connected to the copper or black screw.
This arduino based 3 way traffic light controller is a simple arduino diy project which is useful to understand the working of traffic lights which we see around us. Traffic light has proved to be an amazing way to stop the vehicular collisions and control the traffic jams in today s modern era where everyone owns the different types of vehicles. So the on time is 50ms and off time is 50ms.
This is where two switches control the same light or lights.
And this is what you will need for 3 way switch wiring. Here have demonstrated it for 3 sides or ways. This might seem intimidating but it does not have to be. Click image to enlarge.
