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
 
IRL3103 FET operates on logic level input, and is rated at 30V 64 amps. IRL520 is 100V, 10A.
Both are N channel so use them on the ground side of your circuit. Are you running the motors directly from LPT1? Use snubbing diodes.
