Traffic lights are used just about everywhere on busy roads around the world. They can help prevent traffic accidents and keep traffic flowing smoothly in the right direction by regulating the flow of cars, trucks, and other vehicles. The most common traffic light uses red, yellow, and green lights, along with arrows or flashes to indicate which lane should proceed when the lights change from green to yellow or red. Now you can visually see the 4-way traffic light by using the EasyPLC software suite. This provides an easy way of learning PLC programming.
