parallel port opto isolator
Hello..
I need a circuit to interface with PC's parallel port. I want to make a speed control DC motor. I've implemented the closed loop control using delphi. It'll send signals (high or low) for parallel port's pins (data) thru control trackbar.
The program and parallel port are not the problem. I need a simples analog circuit for control the speed of motor DC depending of signal in the pins.
Sorry for the english...
Regards.
