Traffic light software demo

“

- [Instructor] Here we have the ladder logic program in the simulation software. We have the values of the truth table inside the binary table. Taking from bit three, word zero to bit three, word four. Now for the LEDs of the traffic lights. Try to match the colors to the one we have in the slides. So north and south, we have the red in bit zero, yellow in bit one, and green in bit three. East and west we have red in bit three, yellow in bit four, and green in bit five. So you can simply change the color of the LEDs by right click, and then choose the corresponding colors for each one. Now as soon as I download the program, I go online and download it, once I hit run, the process starts. So go through the red and then green for the east and west, and then it toggles between the traffic lights.
