The project illustrates how an inexpensive logic analyzer is made to connect with a PC using the parallel port. The project illustrates how an inexpensive logic analyzer is made to connect with a PC ...

Many designers require that their PCs act as complete control systems without any internal hardware. For this function, users need at least one channel of analog data acquisition to monitor the ...

Featured in this project is the control of a stepper motor with its speed, direction, and step size by sending some signals through the parallel port. The project provides better understanding and ...
