Trafficlight

[inuyasha84]

Hello I have realized this trafficlight with the purpose to do some practice with labview.
Could this be considered as a State Machines in the way it is thought? It works 3 times doing Green->Yellow+Red-->Red-->Red+Yellow-->Green and so on.

Can you suggest me other implementations? 

Thank you

This is no state machine. This is a static sequence which is repeated several times.

The issues with such approach are:

- How do you terminate prematurely as such that the program can shut down gracefully?

- How flexible is the code if you have to change order of execution?

- How readable will the code be if you add 1, 2, .., 10, ...100 new "cases"?

You should use a real state machine. You can find an example in the LV template browser which you open by selecting File >> New.

(NOT New VI!)

hope this helps,

Norbert

PS: Do not use variables.
