LabView Project for Data Acq class

[symbolX]

Hi,

I'm in a PC Data Acquisition class in college and there is a project that has to be done in Labview.
The instructor has not given much detail other than it has to use: Digital in, Digital out, Analog in, Analog out.
There are no guidelines other than that.
I was wondering if anyone can throw some ideas out there, because I have none. Nothing too complex though.

Thanks

Hi
sounds like a very open project

Suspect you have not mentioned all the details

What acquistion card are you thinking/allowed to utilise.
What version of labview are you programming in?
What functionality do you have to program in labview?
You mentioned digital in /out is this to control or monitor

likewise with youe analog components.

in a broad nutshell  need more information

Well, first of all, do you have access to a computer with LabVIEW on it and if so what version (LabVIEW version and whether basic, professional, etc.)! Then, what DAQ hardware is installed? The best answer here is a National Instruments multifunction DAQ card, because there are a lot of examples, in the LabVIEW pull down examples, for their hardware, and a multifunction board may give you the digital I/O and analog I/O capabilities in one card. Now as to what to do with them, well if you have some external hardware, ideally some trainer board, or a protoboard you can build a circuit on, you can then have some digital/analog combination that you can provide the stimulus to (digital level or an analog signal) and measure the resultant.

Give us more info and we will give more "Hints", but as mentioned in other posts over the years, we won't do the bulk of anything we determine is a project (academic or work), just help point you in the right direction.

How about a mock up of a system that manages a house  (e.g. security, heating...)

Digital inuts could be the status of the windows and doors, open vs closed.  Leds could be used to indicate thier status  If a window opens when you are not at home, an alarm souds, dog barks, walls of room close to crush intruder. 

Analog in could be temperature.  You could use your analog out to drive a light bulb to simulate a furnace. You might be able to use a PID loop to act as your thermostat to maintain a set temperature.

One feature may be to let the cat out, say at 6:00 AM.  You could use an automatic "cat-apult" to help Kitty on his way.

Good Luck

Thanks for responding.
I don't expect anyone to do any work for me, just polling for ideas for the project.
We have LabView 8.2 in the lab I'm working in. We also have the new Elvis DAQ board to interface with.
The professor I have this lab with is not real specific other than what I mentioned (didn't even give us a handout).
Basically says, "Do a project". Ok... lol.
So I'm gathering its something like interfacing with hardware on this board perhaps a temperature sensor or something and then gathering data in labView and performing some meaningful calculation (i.e. displaying the temperature in fahrenheit/centigrade). Someone's already doing this though, so I can't use that. But perhaps this gives a better insight into the requirements.

**I'm pretty sure there's a multifunction DAQ card installed in the PC. Forgot to mention that.
