how to make labview run LED lights and also a webcam

[klkanth]

i have labview 8.2 version. iam a graduate student at university of alabama at birmingham. our computer has windows XP. for our project we need to switch on and off LED lights for different periods of time. at the same time record the eye using a webcam (for processing later on).  iam new to labview, i just barely finished the tutorial. but i am unable to find an example or write a program for running labview for this purpose.

could you please help me to write the program. i donot know much about labview so i request help as a total beginner. my professor is wanting me to write the program asap, so an immediate reply would be greatly appreciated

thank you very much in advance

This should get you started.

Sounds like you just need a couple of loops. The first loop is to control the LEDs, and the second is for the webcam. However, before figuring out what to code, you need to define the problem a little better:

• Are all the LEDs controlled at the same time at the same rate, or do the LEDs have different update rates?
  
• How many LEDs are there?
  
• Is there any relationship between the state of the LEDs and the webcam?
  
• You said that the webcam is recording the eye. What eye?
  
• What are you using to control the webcam?
