Educational USB data acquisition card

Abstract

This project aims to design and implement a general purpose educational data acquisition card . the card is interconnected with computer through the popular universal serial bus (USB) , which has become an important widely used tool in science and technology. This card was intended to be used to control many applications which enable users, including teachers and students, to perform a variety of experiments, four applications have been implemented and tested which are: fan , heater , stepper motor , and alarm system. The microcontroller PIC18f4550 was used in building the data acquisition card because of its capability to provide the entire necessary control signal for the applications presented. Visual c++ 2008 software was used as a tool for graphical user interface , to enable users to interact with the system in efficient manner.
