Hi.
I have designed a stepper motor and photocell circuit which will follow light when seen by the photocells. I already programed everything and am just having touble with finding a way to use the 3.5 to 4 volts from the parallel port of my computer to switch a higher voltage when needed. i do not want to use a relay (if that is what they are for). only electronics
thank you
