Hi,

I want to know how do I import text files to labview and with the help of an Daq card, give a signal to a analog output E.g. a buzzer.

Is your text file with the postfix as "*.txt"? If it's "*.txt" file, you can use open/create/replace file.vi and read text file.vi that in the File I/O palette to read it. There are a lot of examples. You can find them by NI Example Finder.

For the DAQ question, the signal that generates by DAQ card can not be power driver. This means your buzzer need power supply, and you can use any waveform as output signal.
