Learning is more interesting whilst doing a project, hence why i chose to do a traffic light. Yes it is fairly simple, and be done with a few lines of C and Arduino. The idea is just to learn more about PLCs. The PLC i am going to use is a Siemens Logo 8.
I will be posting as i progress through the project.
After following the introductions to Logo in the Siemens website, making it run like a traffic light simply involved coming up with the solution given the commands available. I have attached the ladder logic program, it has the same sequence as a normal traffic light except I have shortened the whole cycle.
