Lab 3 Programming Structures - Timing Issues
I. Objective:
To give the student a lesson in using user-defined Sub-VIs, graphics, local/global variables, and other programming structures in LabVIEW.
II. Procedure:
Create a simulation traffic light at a four-way intersection. Import a picture for the intersection from the web page or make one of your own. To import a picture, simply cut and paste it onto the front panel. On top of this picture of the intersection, place your traffic lights. This traffic light should have
Control |
Function |
Slide control A | Controls duration of N-S Green Light |
Slide control B | Controls duration of N-S Yellow Light |
Slide control C |
Controls duration of E-W Green light |
Slide control D |
Controls duration of E-W Yellow light |
Using these four controls, you should be able to figure out the duration of the E-W and N-S red lights. Remember that the North-South and East-West traffic lights have to be in sync with each other (i.e. both traffic lights cannot show greenthis would cause an accident).
