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 nowadays. 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.
