Data Acquisition Question

Recommended Posts

20 years ago as a high school kid I figured out how to get my Apple IIE to plot a graph on the screen with basic that measured the voltage that a small light sensor produced. I have since been interested in data acquisition but have never gotten back to it. I am overwhelmed with the terminology and information available nowa days. What is the simplest way to connect my pc (hardware) with a water pressure sensor and write a program to monitor it visually. Should I use excel? Visual basic? Java? If I purchase a mac what is available from them? Any help would be greatly appreciated.

there are many languages and any would work, I would use a Pic processor to grab what ever information and send it over serial (need usb to serial converter) then pick a language you like

java, mono(C#, VB, ironpython, boo), c++, objective C would all work, just pick one and read up on it..

this may help it uses java to read a serial port..

as for drawing graphes.. that is after you can do this much..
